Trim-Tex Miter Marker User Manual

Trim-tex miter markers

Trim-Tex now has 3 Miter Marking Tools. All the tools can be used for marking 90º and 135º off

angle corners. The 350 Miter Marker (#0922) works with all 350 Bull products. The ¾" R. Miter
Marker (#0932) works with ¾" R. Bullnose Corners, Bullnose Super & Giant L Beads & Bullnose Fast
Caps. The Chamfer Marker (#0943) works with Chamfer Bead and Chamfer Stop. The directions for all
three are listed below as all products function identically.

Everyone measures marks & cuts differently so you may need to practice on a few

pieces first.

All Miter Markers come with alignment edges

that are marked with an arrow to allow you to mark the bead to fit any opening. To properly use the Miter
Marker you will need a sharp pencil and tin snips. You will also need a small T square for Bullnose L
Beads & Fast Caps.

detailed installation instructions. Ideally you should have a / " gap that will need to be caulked with a paintable acrylic caulk. This will allow some wall
settling without causing hairline cracks in the compound.
