Review: Feels Strong and Confidence-Inspiring Straight Out of the Box - Alright, I go through padlocks like they’re going out of fashion. I don’t treat them gently — they’re permanently exposed to the elements — so they tend to fail sooner rather than later. That said, the quality of this one compared to others is immediately noticeable. It’s one of those moments where you think, “Oh yeah, this is actually nice to use.” The lock has a reassuring weight to it — solid and heavy-duty — but not so much that it’s impractical. You wouldn’t want it in your pocket all day, but for a gate or outdoor use, it feels spot on. I bought this because my previous lock (also a Master Lock, but a more basic laminated style) had become stiff and awkward to open over time. This one is the complete opposite. The key goes in smoothly, turns easily, and it pops open cleanly and assertively — no forcing, no fiddling. That alone makes a big difference in daily use. Is it more expensive than you’d ideally like? Probably. Around £13 for a gate padlock feels a bit steep at first. But once you factor in ease of use, build quality, and reliability, it starts to make sense. After using it, my opinion on the price changed completely — I’d happily buy another one in a heartbeat. If it ever lets me down, I’ll update the review — but so far, I’m genuinely impressed. 👍 Review: Seems like a sturdy lock - Seems like a good product, very sturdy and looks like it is proofed against weather, but only time will tell if it will not get rusty and will not stuck. ## Features - Warning:To be used under the direct supervision of an adult - PADLOCK APPLICATION: For indoor and outdoor use; covered laminated steel padlock is best used for storage units, sheds, garages, fences and more. - DUAL-ARMOR PROTECTION: Small padlock has a laminated steel core with a weather resistant cover that protects against snow, rain, dirt, mud, grime and salt. - HIGH SECURITY APPLICATION: Lock has a 4-pin cylinder for increased pick resistance and a Tough-Cut octagonal boron-carbide shackle that is 50% harder than hardened steel. - DURABLE DESIGN: Covered laminated steel padlock has dual ball bearing locking for maximum pry resistance and a covered keyway and shackle seals for added weather protection. - SPECIFICATIONS: (H x W x D) 5,8 x 4,9 x 2,7 cm ; shackle (H x W x D) 3,8 x 2 x 0,8 cm ; 1 padlock ; 4 keys. - Limited lifetime guarantee ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0035RR008 | | Best Sellers Rank | 1,030 in DIY & Tools ( See Top 100 in DIY & Tools ) 3 in Keyed Padlocks | | Brand | Master Lock | | Colour | Black | | Control Method | Touch | | Controller Type | Key | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 4,675 Reviews | | Finish | Powder Coated | | Global Trade Identification Number | 03520190930392 | | Included Components | 1 Padlock and 4 Keys | | Item Dimensions | 27 x 49 x 58 millimetres | | Item Type Name | MASTER LOCK High Security Padlock [Key] [Covered Laminated Steel] [Weatherproof] [Medium Shackle] M115EURDLF - Best Used for Storage Units, Sheds, Garages, Fences | | Item Weight | 272 g | | Item dimensions L x W x H | 27 x 49 x 58 millimetres | | Lock Type | 4-pin cylinder | | Lock type | 4-pin cylinder | | Manufacturer | Master Lock | | Manufacturer Warranty Description | Limited lifetime guarantee. | | Material | Laminated Steel | | Model Name | M115EURDLF High Security Padlock | | Model Number | M115EURDLF | | Number of Pieces | 1 | | Part Number | M115EURDLF | | Recommended Uses For Product | Garages, Gate, Shed, Storage Units, Tool Box | | Recommended uses for product | Garages, Gate, Shed, Storage Units, Tool Box | | Shape | Square | | Special Features | Anti-Corrosion, Cut Resistant, Scratch-Resistant, Weather Resistant | | Special feature | Anti-Corrosion, Cut Resistant, Scratch-Resistant, Weather Resistant | | Style | Medium Shackle + Weatherproof + Rustproof | | Unit Count | 1.0 count | ## Product Details - **Brand:** Master Lock - **Item dimensions L x W x H:** 27 x 49 x 58 millimetres - **Lock type:** 4-pin cylinder - **Material:** Laminated Steel - **Special feature:** Anti-Corrosion, Cut Resistant, Scratch-Resistant, Weather Resistant ## Images ![Heavy Duty Padlock, Security Level 8/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - Image 1](https://m.media-amazon.com/images/I/516eg34U2-L.jpg) ![Heavy Duty Padlock, Security Level 8/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - Image 2](https://m.media-amazon.com/images/I/71QOCrC6fUL.jpg) ![Heavy Duty Padlock, Security Level 8/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - Image 3](https://m.media-amazon.com/images/I/71u56vX3RwL.jpg) ![Heavy Duty Padlock, Security Level 8/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - Image 4](https://m.media-amazon.com/images/I/81FhL71a7XL.jpg) ![Heavy Duty Padlock, Security Level 8/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - Image 5](https://m.media-amazon.com/images/I/61BcJbS0CgL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will the padlock weather easily and is it suitable for my house's side gate?** A: I have this on my side gate and have had no problems since purchased in 2016. no sign of rust weathered well over winter and regularly used. **Q: What's the CEN rating please?** A: Excellent **Q: Is it possible to buy two lols that have the same key?** A: All the keys are the same **Q: What is the clearance on the inside of the shackle.

Obviously the lock never gave out however not being able to unlock it again prove to be a pain and i had to destroy it with an angle grinder so good for stopping access bad for use after an attempted robbery. The small flap that covers the keyhole is also quite susceptible to falling off randomly which doesent affect the lock so much but does(I assume since it's there for a reason) hinder the weather proof ability ## Frequently Bought Together - MASTER Lock Heavy Duty Padlock, Security Level 10/10, Outdoor, Keyed, Covered Laminated Steel, Weatherproof, Medium Shackle - TERF® Heavy Duty Hasp and Staple Set Black 190mm Security Door Padlock Latch Including Fixing Screw for Use with Outdoor Cabinet Cupboard Cage Gate Shed Commercial and Multi Purpose Use - 190mm - Master Lock 7804EURD Laminated Padlock with Key and Thermoplastic Cover, Black, 7,8 x 4 x 2,9 cm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/53072722-heavy-duty-padlock-security-level-8-10-outdoor-keyed-covered](https://www.desertcart.us/products/53072722-heavy-duty-padlock-security-level-8-10-outdoor-keyed-covered) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-20*
