Mounting The J-Hook
1.
Properly securing the J-Hook is critical for ensuring the safety of the ramp
system. The J-Hook is responsible for supporting the top of the upper most
ramp section. The J-Hook also ensures the ramp does not pull away from
the landing.
2.
I
f connecting a ramp run to a Harmar
platform, the J-Hook should first be installed
to the platform with provided bolt, washer,
and
1/2”
nut.
The platform is predrilled in
the middle of all sides for the J-Hook
attachment.
3.
If your ramp run will be connecting to an existing
structure, you must first mount the J-Hook to
that structure. The top edge of the J-Hook should
be level with the landing. The J-Hook must be
plumb vertically once securely fastened.
4.
You are responsible for determining the appropriate fastener for the
material you are attaching to. Check
local codes and hardware specifications.
When working with brick or other
unstable materials, it is recommended
to add two leg brackets with legs to
support the load. This does not replace
the need for the J-Hook.
TIP: When installing J-Hook onto a turning platform, you can mount it off center to provide an increase in
turning radius. This requires that you drill your own holes into the platform for the J-Hook attachment.
