Instructions
To properly use
the Miter Marker on 350 Bull Corner Bead you will need a sharp pencil
and yellow aviation tin snips. Place the Miter Marker on the bead as
shown in Figure 1.
The 350 Bull Miter Marker comes with alignment edges to allow you to
mark the bead to fit any opening. The alignment edges are marked with
an arrow. See top right. First measure the opening inside corner to
inside corner as shown in Figure 2. Mark dimension A on the piece. The
1st mark should be at least 1” away from the edge to leave enough
bead to be cut off. See Figure 3.
To mark for a 90º corner, use the outside edges of the Miter Marker.
Slide the tool along the piece until the alignment edge, marked with
an arrow, lines up with the pencil mark. Now mark the radius with a
pencil. See Figure 4A. For a 135º off angle corner use the inside
openings of the tool. Slide the tool along the bead until the inner
alignment edge lines up with your pencil mark. Mark the radius with
your pencil. See Figure 4B. (Not Shown.) To make a straight mark for
a butt joint, use the middle slot marked STRAIGHT.
Snip to the marks you have made and snip back the legs as shown in Figure
5. Do not completely cut away the pencil line or the parts may come
out too short. Everyone measures, marks and cuts differently so you
may have to practice on a few pieces. Install the bead with staples
and/or spray adhesive. Ideally you should have a 1/16” gap that
will need to be caulked. This will allow some wall settling without
causing hairline cracks in the compound. Use a paintable acrylic caulk. |
