MOUNTING TO WOODEN STUDS
The wall plate can be mounted on up to three wooden studs. Using a high-quality
wall stud finder, find the location of the wall studs. Mark the centre of the wall stud
(an edge to edge stud finder is highly recommended).
Use a level to draw a vertical line down the centre of the stud. Use the template to
mark the holes. Drill 8mm (5/16”) holes to a depth of 90mm (3 1/2”). Use the lag
bolts to attach the wall plate to the wall (as shown in fig. 2.1).
Use the template to mark the centre of the holes on the wall. Drill 14mm (1/2”)
holes to a depth of 90mm (3 1/2”). Insert the anchors into the holes, making sure
the anchors are flush with the wall, as shown in fig. 2.2. Install the wall plate to the
wall using the wood screws. Please make sure the wall plate is level, and tighten all
fasteners. See fig. 2.3 for clarification.
MOUNTING TO CINDER BLOCK WALLS
WARNING
- Cinder block must meet ASTM C-90 specifications
- Mount to solid portion of block, minimum 25mm (1”) from the sides
- Never drill into mortar joints!
- Use standard drill set on slow speed/high torque setting. Do not use hammer drill
on cinder block.
- Verify that you have a minimum of 35mm (1 1/4”) actual concrete thickness in the
mounting hole, before inserting the wall anchor.
The anchors must be seated firmly against the concrete masonry. If mounting to a
masonry wall covered with drywall/plaster, counter bore a hole through the drywall/
plaster around the mounting hole location, so that the anchor can be seated directly
against the cinder block.
Tighten the lag bolts so that the wall plate is firmly attached to wall, but do not
overtighten. The lag bolts can be damaged by overtightening which greatly reduces
their holding power. The final tightening of the lag bolts must always be done by
hand, with a ratchet wrench and socket.

MOUNTING TO CONCRETE/MASONRY
WARNING
Never drill into a mortar joint.
The concrete must be 2000PSI minimum density.
The anchors must be seated firmly against the concrete or masonry. If mounting to a
masonry wall is covered with drywall/plaster, counter bore a hole through the drywall/
plaster around the mounting hole location, so that the anchor can be seated directly
against concrete or masonry. This is shown in fig. 2.2.
