Used it a few times and it's perfect. ### ⭐⭐⭐⭐ You would think it would be simple *by M***G on 8 September 2018* When assembled with the right string, its 100%. As others note, getting the string in is a pain. My solution was poking through with a bent paperclip, but the supplied string is so fine that knotting it big enough to prevent it slipping out is close to impossible and having done it, the bob cocks over to one side opposite the knot. Useless. Throw the supplied string away and poke the thickest you have got through the hole and bob is now your uncle. ## Frequently Bought Together - Amtech G4100 Plumb bob and line - CORAL 69500 Paperwiz 3-in-1 Wallpaper Tool, The Original, Yellow - Harris Seriously Good Paperhanging Wallpaper Scissors | 12" --- ## 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.jp/products/48522967-amtech-g4100-plumb-bob-and-line](https://www.desertcart.jp/products/48522967-amtech-g4100-plumb-bob-and-line) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-16*
