Empire's True Blue 254mm heavy-duty aluminium T-Bevel is most commonly used to measure, transfer and mark angles. The T-Bevel’s handle is made from a single piece of billet aluminium for superior durability and longevity. Featuring an adjustable 250mm stainless steel blade which will never corrode or rust. The stainless steel blade is retained with a low profile wing nut that securely locks the blade in the desired position, keeping it in place as you transfer the measured angle and will not move when marking against the blade. Made from high grade materials, with a premium finish, this True Blue T-Bevel was designed to last a lifetime, which is why it carries the Empire Lifetime Guarantee.
