Supplemental instructions for the Wall -mounted Treadwall
The basic differences between a standard Treadwall and the wall-mounted version are in the
support frame and the angle-changing mechanism.
Support frame:
The wall-mount version has one-piece side frames that are considerably narrower than the
standard Treadwall frames. The frames are deep enough at the base to support the full weight
of the Treadwall, but in use, they must be attached to a backing wall for lateral support and to
provide front-to-back stability. The accompanying drawing, TWM-04, shows our
recommendations for attaching the frames to the wall. Using 2x8 backing plates as shown in the
diagram works very well and is highly recommended.
Steps:
1) Prepare backing plates and attach them to the wall as recommended
2) Assemble support frame – two large side frames and two horizontal bars in the back. The
horizontals have L-shaped brackets at the ends, and they should be oriented so that the “Ls”
are toward the back of the frames.
3) There are flat x-braces, as shown in the drawing TWMM-04. These braces are attached with
the same bolts that attach the horizontal bars to the frame. The bolt heads should be at the
back of the frame with the hardware in this order, from back to front: Bolt head – washer –
horizontal L-bracket – frame upright – x-brace – washer – lockwasher – nut.
4) Once assembled, the frame is free-standing, but there is not a great deal of lateral support
until the x-braces are tightened-up. Leave them a bit loose until the frame is mounted to the
wall.
5) Push the frame into place against the backing plates and drill ¼” pilot holes for the top four
lag screws. Screw the top horizontal to the top backing plate with 3/8 x 3 ½” lag screws with
washers and lockwashers. Use the provided shim-washers to space the horizontal out from
the backing plate by about 3/8” (4 washers at each lag bolt). This provides clearance for the
bolts at the ends of the horizontals.
6) The bottom of the frame can be slid back and forth with a chunk of 2x4 and a hammer until
the frames are true and perpendicular. Use a carpenter’s square to make sure the frame is
square with the horizontals. When it is all trued up, put in the bottom four lag-bolts. Shim
these lag bolts like the top ones.
7) Tighten the x-brace turnbuckles evenly.
Angle adjuster:
The rest of the Treadwall assembly is similar to the standard Treadwall, as shown in the
Treadwall Assembly Manual, with the exception of the angle adjuster. Drawing TWM-01 and
TWM-13 show how the wall-mount angle adjuster works. Simply bolt the angle bearings to the
channels as shown and attach the swinging link to the back frame. The Treadwall is easily
adjusted to a slab or overhanging angle by rotating the crank handle.
