Core Function: Multi-functional stair tread layout gauge with combined multi-size telescopic aluminum bars, freely adjustable for stair tread width and riser height. Equipped with 180 angle scale templates on both ends to accurately copy stair bevel and step dimensions. Complete set includes double 8/12/16-inch sliding bars, angle rulers, lock knobs, screws and washers, matched with hard shockproof storage case. Carpenters and decorators can quickly copy shapes on-site without repeated measuring, ideal stair installation layout tool kit for cross-border home hardware export.
Material & Craft: Telescopic sliding bars are integrally extruded from thick aerospace aluminum alloy, lightweight yet high-strength, resistant to bending and deformation with red anodized anti-wear & anti-rust surface. Tread templates at both ends are thick stainless steel plates with deep laser-etched inch marks and 0-180 protractor scale, permanent clear markings resistant to grinding and abrasion. Lock knobs are made of high-strength plastic with built-in metal threads to avoid slipping after frequent tightening. The matched ABS hard storage box features honeycomb buffer foam inside, shock and compression resistant for long-term construction site storage.
Structure Design: 3-size sliding bar combination (2pcs each of 8/12/16 inch), usable individually or spliced together with a maximum adjustable total length of 31.88 inches. Dual-end stainless steel angle templates with full length ruler and protractor plate precisely copy any stair corner and slope. T-type knob screw quick-lock structure with pressure-distributing washers to prevent shifting and slipping after locking. Modular splicing design allows adding or removing bars to fit narrow or wide stair treads. All accessories are stored separately for neat storage, simple assembly for single-person stair dimension sampling.
Specification: 2pcs stainless steel tread scale templates; 2×8in sliding bars, 2×12in sliding bars, 2×16in sliding bars; 10 lock knobs, 10 fixing screws, 12 anti-slip washers; 1 ABS hard shockproof tool case. Slider thickness: 0.16 inch, template thickness: 0.12 inch, max adjustable length 31.88 inches, measuring angle range 0-180 . Full set with all assembly accessories, universal English export packaging labels.
Use Advantage: Multi-length bars for free splicing, compatible with all stair sizes; 8/12/16 inch bars work alone or combined to fit narrow treads, wide landings and extra-long stairs with max 31.88in extension covering most residential and commercial stair types. Integrated 0-180 protractor on stainless steel templates eliminates extra angle finder, locates stair corners and bevels in one step for error-free layout and less cutting rework. Thickened aluminum bars resist bending under heavy load; knob screws with washers lock dimensions firmly without shifting during transport. Full accessory kit with shockproof hard case prevents loss and damage for outdoor construction use. 4-step easy assembly, hand-tighten knobs without extra tools, drastically boost efficiency for stair paving and wood cutting. Deep laser-etched permanent scales resist wear from cement and grinding, clearer and longer-lasting than ordinary printed rulers.
Application: Solid wood stair installation, tile stair tread laying, stone stair processing, carpentry stair cutting, villa commercial stair layout, duplex indoor stair renovation, stair handrail positioning, step skirting cutting, on-site decoration dimension copying, home DIY stair making.
