A sliding T-bevel is an adjustable gauge for setting, testing, and transferring angles.
The handle is made of wood or plastic. The metal blade pivots and can be locked at any
angle - just loosen and tighten the wing nut. The end of the blade is angled at 45 degrees,
for use on mitered corners.
Using a Sliding T-bevel
To record an existing angle, loosen the wing nut, hold the handle against one surface,
and press the blade against the other. Tighten the nut to lock the blade in place. To
set the square to a specific angle, loosen the wing nut, hold the handle against the base
of a protractor, and move the blade to the desired degree setting. Retighten the wing nut.
To test an angle, extend the blade fully from the handle when testing angles against the
outside edges of the tool. Otherwise, the heel of the blade could cause an inaccurate
reading.
Purchasing
One sliding T-bevel model has a locking wing nut at the top of the handle. On a second
style, this nut is positioned at the handle's base. An advantage of the latter is that
the nut can't interfere with taking readings. A disadvantage, however, is that you need
both hands to secure the blade. (You can accomplish this with one hand with the top-locking version.)

Bevel square
Substitutes
An alternative to the sliding T-bevel is an angle gauge. You can use this handy device to
read, measure, and mark inside or outside angles from 0 to 360 degrees. You can also use
it to check angle accuracy, squareness, straightness, and to set tool angles.
