Transfer Exact Stair Tread Shapes – Without Guesswork
This stair tread template tool captures the exact width and angles between two walls or stringers and lets you transfer that shape straight onto your board. Adjustable steel rulers, a smooth sliding body and extendable aluminium bars make it useful for stairs, shelves, cabinets and custom furniture.


The challenge
Walls are rarely perfectly square
Fitting a stair tread, shelf or worktop between two walls usually means measuring, re-measuring and still ending up with gaps. Every corner can be slightly off, and tape measures cannot capture an angle.
This tool copies the real shape of the opening – width and both end angles – so you can mark it onto your material in one go.
How it works
Measure, lock, transfer
Any angle
Adjusts to every angle you need
The rulers pivot freely, so the tool follows sloped walls, skewed stringers and odd corners. That makes it just as handy for cabinets, shelving and built-in furniture as it is for staircases.

Key features
Built for precise, repeatable work
Aluminium alloy body
Light to handle yet sturdy enough for everyday workshop use.
Sliding connectors
Machine screws and knobs let you lock the setting firmly in place.
Modular length
Join or remove bars to shorten or extend the tool for each project.
Smooth sliding
Quick adjustments that save time on every tread or panel.

Flexible sizing
Shorten or extend in seconds
The red bars come in three lengths and can be combined in different ways. Use a single short bar for narrow openings, or connect several for wide stairs and long shelves.
Good to know: for the most accurate result, tighten all knobs before lifting the tool out of the opening.
