Installing stair treads can be challenging since most stairs aren’t perfectly square. The BULLET Stair Tread Tool eliminates the guesswork, helping you measure and cut each tread to the exact angle and length you need.
There are several features that make this tool stand out in the industry:


It’s perfect for professional installers and DIYers, ensuring tight, accurate fits every time in five simple steps.
Step 1: Cut and Prepare Your Board
Start by cutting a board 2.5 inches shorter than the total width of your stairs. We recommend using a VAUGHAN Bear Saw® for quick, effortless cutting. The BULLET Stair Tread Tool is designed to work with boards up to a standard 2x4, making it more versatile than similar tools on the market.
Step 2: Attach the Board to the Stair Tread Tool
Slide your cut board onto the Stair Tread Tool. The spring-loaded crossmember makes attachment quick and secure, holding the board firmly in place while you work, while saving you time and ensuring consistency.
Step 3: Measure the Stair Tread
To find the correct dimensions, loosen the knobs and press each side of the tool into the corners and edges of the stair tread. Once both sides are flush against the walls, tighten the knobs. You’ll now have the exact angle and length for that specific step with no guessing!

Step 4: Mark Your Cut Lines
Place the tool on your flooring material and align the pointed ends with the edge of the tread. Use the sides of the tool as a guide to mark your cut lines clearly. The bold, easy-to-read markings make transferring measurements fast and accurate, ensuring a perfect fit with minimal adjustment.
