Serviceable Quality Selection: Our stair gauge is made of high-quality aluminum alloy with an anodized surface, providing a stable structure, durability, and reliability. It is sturdy yet lightweight, resistant to breaking or deformation, making it a practical tool for accurate layout work. Accurate Mark and No Slip: The speed square holder features a hexagonal plane, offering better edge alignment than circular designs, and its increased height helps keep the ruler perpendicular to the material for more precise markings. The thumbscrew enhances friction and prevents slipping, allowing secure handling even when wearing gloves. Versatile to Apply: These stair gauges are functional and multi-purpose, ideal for stair stringer layout, rafter layout, marking repetitive angles, guiding saws, and other woodworking tasks, helping to improve efficiency in various projects. Clip Design: These framing tools come with clips, allowing you to attach them to your belt, work bag, or wall hook. This helps prevent loss or damage and ensures easy access when needed. Note: Measurements are manually taken; please allow a 1–3 cm variation. Due to differences in lighting and display settings, some color variation may occur.
