Its adjustable tension bands and soft rubber clamps protect your gear while ensuring perfectly tight line spooling. Compact and rust-resistant, this ABS tool fits easily in any tackle setup, making it the ultimate must-have for anglers who demand precision and convenience on every trip. ## Description Kastking Radius line spooling tool has a unique compact design which gives you a quick and easy way to spool both casting reels and spinning reels without twisting the fishing line, and without removing the reel from your rod. The Radius fishing line winder spooler is designed to position the filler spool parallel to the rod for spooling casting reels. This orientation permits line to unroll from the filler spool and roll directly onto the casting reel spool without twisting the fishing line during the process. Our unique tension band system allows for quick adjustments to the line tension being applied during the spooling process to ensure the line is tight on the spool. An integrated slide lock makes it easy to quickly adjust to wide or narrow spools. For spinning reels, the filler spool is positioned perpendicular to the rod which allows the fishing line to un-coil from the filler spool and coil onto the spinning reel spool. This prevents the line from twisting as it is being spooled onto the spinning reel. The adjustable tension band is used to apply the ideal pressure to make sure the line lays down correctly on your fishing reel and it is not too loose. Double injected rubber clamp points help to prevent any damage or marring to your rods. Instructions are molded into the body of the unique Radius line spooler to assist with the proper setup for both spinning and casting reels. Wind fresh line Spool on your reels anywhere at any time with the compact KastKing Radius line spooling tool! Review: success every time - I honestly don't know if I'm using this thing 100% correctly. But I've used this to spool multiple reels and I have not had any issues with a rats nest on casting or any other usage really. The price was good and its pretty easy to use. The little elastic bands that go around the spool of line do a pretty great job at keeping tension. I would recommend for those that want easily spool their own reels without having to get too creative. Review: Excelente producto - Excelente el producto ## Features - Key Features – Unique patent pending design - Spool spinning reels and casting reels without fishing line twist – compact design for easy storage and portability – 1/4lb spool capacity – Soft touch clamping points protect rod blanks – adjustable line spooling tension bands ensure that line is spooled tightly on the reel - works with monofilament, fluorocarbon, and braided fishing line. - PATENT PENDING LIINE SPOOLING TOOL– The innovative KastKing patent pending line spooler design is simple to use and can spool both spinning reels and baitcasting reels without any line twist. Rubber coated clamp points firmly grip nearly any size rod without damaging your fishing rod and tension bands can be adjusted to apply the ideal line tension during the spooling process. Made with non-rusting ABS materials. - NO LINE TWIST – The Radius design allows fishing line to come off your filler spool and directly onto the reel spool without any twist in the fishing line. When spooling a casting reel, the line comes off the top of the filler spool and winds directly onto the top of a casting reel without changing the coiled memory of the line. For a spinning reel, the line is un-coiled from the filler spool and coiled directly onto the reel spool in the same fashion. - SPOOLING MADE EASY – Place the tension band on a spool of line, clamp the Radius to a rod, using the threaded t-handle mount up to a 1/4lb spool of line on the tool, attach the fishing line to the reel spool, and crank the handle to fill your fishing reel with your favorite fishing line. Instruction cues are molded into the tool as a quick reference to ensure your set up is correct for spinning and casting reels. - COMPACT DESIGN – The small design of the KastKing Radius line spooling tool makes it easy to store with your fishing gear at home or take on the road. The threaded t-handle stores inside the Radius and the tension band can be attached to the Radius to ensure all the components are stored together. The Radius is always there when you need to spool line. KastKing Radius Line Spooler compact design easily fits in your tackle bag, jacket pocket, or boat or truck glove box. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Y8SQ64Y | | Brand | KastKing | | Brand Name | KastKing | | Color | Orange | | Colour | Orange | | Customer Reviews | 4.3 out of 5 stars 1,736 Reviews | | Fishing Line Type | Braided | | Fishing Technique | Spinning | | Fishing technique | Spinning | | Hand Orientation | Ambidextrous | | Hand orientation | Ambidextrous | | Handle Material | Acrylonitrile Butadiene Styrene | | Item Weight | 0.31 Pounds | | Item weight | 0.31 Pounds | | Line Capacity | 8/300 | | Manufacturer | KastKing | | Manufacturer Part Number | KK-KTALIMSPL-01 | | Material | Acrylonitrile Butadiene Styrene (ABS) | | Material Type | Acrylonitrile Butadiene Styrene (ABS) | | Model Name | Radius Line Spooler | | Other Special Features of the Product | Rust Resistant | | Size | L | ## Product Details - **Brand:** KastKing - **Colour:** Orange - **Fishing technique:** Spinning - **Hand orientation:** Ambidextrous - **Material:** Acrylonitrile Butadiene Styrene (ABS) ## Images ![KastKing Patented Radius Fishing Line Spooler, Reel Spooler | Easy to Use, Fits Spinning & Baitcasting Reels, Patent-Pending Design, No Line Twist, Fishing Gear, Great Fishing Gifts - Image 1](https://m.media-amazon.com/images/I/61aXyu8JIyS.jpg) ![KastKing Patented Radius Fishing Line Spooler, Reel Spooler | Easy to Use, Fits Spinning & Baitcasting Reels, Patent-Pending Design, No Line Twist, Fishing Gear, Great Fishing Gifts - Image 2](https://m.media-amazon.com/images/I/61uNJjilNSS.jpg) ![KastKing Patented Radius Fishing Line Spooler, Reel Spooler | Easy to Use, Fits Spinning & Baitcasting Reels, Patent-Pending Design, No Line Twist, Fishing Gear, Great Fishing Gifts - Image 3](https://m.media-amazon.com/images/I/611SyshNYcS.jpg) ![KastKing Patented Radius Fishing Line Spooler, Reel Spooler | Easy to Use, Fits Spinning & Baitcasting Reels, Patent-Pending Design, No Line Twist, Fishing Gear, Great Fishing Gifts - Image 4](https://m.media-amazon.com/images/I/71G-jkytMbS.jpg) ![KastKing Patented Radius Fishing Line Spooler, Reel Spooler | Easy to Use, Fits Spinning & Baitcasting Reels, Patent-Pending Design, No Line Twist, Fishing Gear, Great Fishing Gifts - Image 5](https://m.media-amazon.com/images/I/61BWYydaBdS.jpg) ## Questions & Answers **Q: Do they sell extra tension band** A: It comes with two, other than that I’m not sure. **Q: None of my med, med-light rods can get the radius spooler to attach securely as the rods are too thin. is there a workaround for this?** A: I would use something like the gripping shelf/draw liner and wrapped it around the rod where you want to attach the spooler. I would try contacting KastKing also about this. they may have a smaller model, or inserts maybe. **Q: Will it hold a larger spool?** A: It is designed to hold larger spools, ie 1000 yards. **Q: Will this work for smaller rods such as Ice Fishing rods that are very small in diameter?** A: The spooler is designed to work with a multitude of rods and different thicknesses. It may be necessary on very narrow rods to move the spooler closer to the reel bale where the rods is thicker. ## Customer Reviews ### ⭐⭐⭐⭐⭐ success every time *by J***5 on 18 December 2025* I honestly don't know if I'm using this thing 100% correctly.

It is however way over priced, it's $15 CDN maybe at best but a great idea and system, if it was $15 I'd probably buy a few just to have on hand on the boat and with my boys and at home. Now for the delivery, I am getting sick and tired of these terrible delivery guys delivering products that look like they were run over by a car. The product showed up in complete shambles like a car tire ran it over, I may still return this. I suspect someone ran it over when they spread out their deliveries at the local Walmart earlier today but this happens at least once a week now with products being delivered in such bad shape. ## Frequently Bought Together - KastKing Patented Radius Line Spooler, Compact Fishing Line Spooling Tool for Spinning Reels and Casting Reels – Line Spooler Spools Fishing Reels Without Line Twist, Great Fishing Gifts - KastKing SuperPower Braided Fishing Line - Abrasion Resistant Braided Lines – Incredible Superline – Zero Stretch – Smaller Diameter – A Must-Have! - Reaction Tackle Braided Fishing Line - Pro Grade Power Performance for Saltwater or Freshwater Fish - Colored Fishing Line Braid for Extra Visibility --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/381820122-kastking-patented-radius-fishing-line-spooler-reel-spooler-easy-to](https://www.desertcart.us/products/381820122-kastking-patented-radius-fishing-line-spooler-reel-spooler-easy-to) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-29*
