Specifications Code: STGRP-4T Size: 4 Tread Open Ladder Height: 1.04M Weight: 6KG Review: Good product - Love the two step ladders, they are great. Review: Great, for going up in the world. - Pretty good value, indeed, I've not found anything better. The treads appears to be quite deep, so should be comfortable to stand on. The construction is sturdy and gives confidence it will not tip. Someone was complaining that too many rules are pictured on the side, but those are simply standard industry H&S guidelines, which are sensible, as too many people have had life changing injuries using a ladder inappropriately. And, it's really meant for electricians (though obviously not limited to that profession) so any ladder movement could lead to tools slipping and hitting a live part; not a good idea at all. The tough plastic tray with a hole or two and a hollow bowl for bits at the top is ideal for the odd tool and screws. You are not meant to stand on the very top tread, which makes sense. Opted for the 6 tread ladder because it meant I didn't have to carry around a smaller ladder only to get somewhere to realise that I needed something taller. So, a good compromise, especially as it is reasonably lightweight. ## Features - ELECTRICALLY SAFE NON-CONDUCTIVE DESIGN – Manufactured from insulated GRP fibreglass, ideal for electricians and electrical work environments. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F124STQ | | Best Sellers Rank | 170,946 in DIY & Tools ( See Top 100 in DIY & Tools ) 296 in Stepladders | | Brand | Sterk Systems | | Brand Name | Sterk Systems | | Colour | Yellow | | Country Of Origin | China | | Customer Reviews | 4.7 out of 5 stars 580 Reviews | | Item Dimensions W x H | 52W x 109H centimetres | | Item Weight | 6 Kilograms | | Item weight | 6 Kilograms | | Load Capacity | 150 KG | | Manufacturer | Sterk Systems | | Manufacturer Part Number | STGRP | | Material | Fibreglass | | Material Type | Fibreglass | | Maximum Height | 4 Metres | | Model Number | STGRP | | Number of Steps | 4 | | Other Special Features of the Product | Heavy Duty, Lightweight, Non-Conductive | | Product dimensions | 52W x 109H centimetres | | Special feature | Heavy Duty , Lightweight, Non-Conductive | ## Product Details - **Brand:** Sterk Systems - **Colour:** Yellow - **Material:** Metal, Plastic, Rubber - **Product dimensions:** 8.1W centimetres - **Special feature:** Heavy Duty, Lightweight, Non-Conductive ## Images ![4 Tread Fibreglass Step Ladder – Lightweight, Stable & EN-131 Certified – Professional-Grade Ladder for Electrical & Industrial Use - Image 1](https://m.media-amazon.com/images/I/61JeKf57mhL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Hi when they are closed what is the hight from the back leg to the front, and I am building a false floor in my van to slide them in** A: The measurement front to back of the closed steps is 14cm. However, at the top when the plastic top is folded, that measures 17cm. Does that help? **Q: Are these Youngman 6 tread fibreglass platform stepladders?** A: Yes **Q: top brace bar is bent? should this product have a bent brace bar.** A: Mines straight **Q: What's the width between the ladders when fully open? I need them wide enough to go across two mini steps to access the loft. Thanks** A: Hi, Adam. Listen, I'm really sorry I've not gotten in touch with you but I've had a stinker of a cold all this week and (according to my wife) I've been all wrapped up in myself Poor , poor me. And, I haven't been into any of my outbuildings, where the ladder is. Anyway, I'm there now and I hope this is going to be of use. Front to back, the distance of the spread at ground level is 50" (1meter 28) and in width, again at the bottom and at ground level it's 22" (57 cms) I do have one grumble about the ladder though. I must have forgotten about the times I've worked back in the States with these glassfiber ladders and it must have gone out of my memory just how heavy they are compared with the good old aluminum ones. There is a substantial difference in weight. This in itself wouldn't be so much of a problem if there more "grip-friendly" surfaces on the thing to carry it round by. But there aren't. The steps have fairly sharp edges and I, wuss that I am, have to remember to wear my working gloves just to carry them round from my van to wherever I'm using them. If I know that I'm not going to be working with voltage then I just take my old ladders. So at least for me that's one star off any review. I sure don't remember glass fiber being that heavy. These ladders are even weightier than my really old wooden ones! Again; apologies for the time I've taken Now, let's get a Benylin down my neck..... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by P***C on 3 April 2026* Love the two step ladders, they are great. ### ⭐⭐⭐⭐⭐ Great, for going up in the world. *by S***T on 21 December 2020* Pretty good value, indeed, I've not found anything better.

Really sound construction with wide, well ridged steps which are solidly riveted to the uprights. Maybe a little heavier than aluminium steps of the same height but probably only by a a kilo or so. The stepladder is slightly tapered towards the top, giving a wider base which, with the firmly attached feet, gives a very good level of stability. the quality of manufacture is very high and I would expect these to last for many years. There's definitely no way I'm going back to aluminium! ## Frequently Bought Together - 6 Tread Fibreglass Step Ladder 30000v - Electricians Heavy Duty Tread EN131 - GRP Step Ladder Sterk Systems - Frog Tape Green Multi Surface Painters Masking Tape, Indoor Painting and Decorating For Sharp Lines and No Paint Bleed 36mm X 41.1m - Excel Electricians Fibreglass StepLadder 3 Tread 1.03m Heavy Duty - Heavy Duty 3 Treads ladder, foldable ladder, folding stepladder, lightweight stepladder, fibreglass stepladder --- ## 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/81266157-4-tread-fibreglass-step-ladder-lightweight-stable-and-en-131](https://www.desertcart.us/products/81266157-4-tread-fibreglass-step-ladder-lightweight-stable-and-en-131) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-21*
