As a DIYer I often work alone and constantly find I'm missing a "third hand". This device often saves me grief. The sliders are easy to set and can hold a screw long enough for me to get the power driver on it. Repetitive marking out is a doddle. The integrated levels come in handy, as does the mechanically locked T square and friction locked multi-angle bevel square. The only (minor) gripe I had was that the centre of the slider groove was not marked on the main bar, so I had to use offset measurements. Great little gadget. PS-Dear SAKER, for your info it is not a king or an emperor - it is a RULE not a ruler Review: Great piece of kit for consistency - I saw a review that said it wasn't square. Well mine definitely is, measured against both a machinist square and a digital protractor. When adjusting, make sure the moving rail is firmly seated in the grooves before tightening up and it'll be bang on. ## Features - 【RELIABLE MATERIAL】Crafted from premium aluminum alloy, our 4-in-1 drilling positioning ruler guarantees durability and resilience.

Well mine definitely is, measured against both a machinist square and a digital protractor. When adjusting, make sure the moving rail is firmly seated in the grooves before tightening up and it'll be bang on. ### ⭐⭐⭐⭐ A useful tool, needs a few minor improvements. *by F***X on 5 July 2025* The tool should be handy, on inspection it appears to be fairly well built, my only criticism is that the numbers which indicate the bevel angles are painted on (all other numbers are engraved/etched), by opening and closing the bevel gauge once, the numbers have scraped off. ## Frequently Bought Together - Saker 4-in-1 Drilling Positioning Ruler, Adjustable 13.78in Multifunctional T Square Ruler, Cabinet Hardware Jig, Marking Gauge Tools for Woodworking, Cabinet Drawer Door Hole Drilling Template - KETIPED 3D Multi-Angle Measuring Ruler,45/90 Degree Aluminum Alloy Woodworking Square Protractor,Drawing Line Ruler, Miter Triangle Ruler High Precision Layout Measuring Tool for Engineer Carpenter,R - Saker Woodworking Scriber Marking Line Ruler, Adjustable Aluminum Alloy Sliding T-Square Ruler,Precision Line Drawing aid Ruler with Angle Adjustment Scale --- ## 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.tn/products/643042926-4-in-1-drilling-positioning-ruler-adjustable-13-78in-t](https://www.desertcart.tn/products/643042926-4-in-1-drilling-positioning-ruler-adjustable-13-78in-t) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
