SIGNATURE SERIES TOP MOUNT POST
HRA-1.24-93 Signature Series Top Mount Post
IMPORTANT: It is the installer’s responsibility to makecertain the structure supporting your posts is able to handle the transferred loads of the railing system (+150 lbs of tension/cable).
Screw length will vary by handrail thickness.
Custom Cable Bullet screw with 3” of continuous threading to maximize
holding strength. Posts MUST be anchored to project structural frame (joists,
blocking). All screw threading should be engaged in structural material. If
mounting directly to structural material, use 3-1/2” long mounting screws. If
mounting through nonstructural material (veneer or trim), use 4-1/2” long
mounting screws.
If no interior blocking, consult a local builder for custom solution to
secure against a 200# concentrated load.
STEP 1 | SET YOUR POSTS
Mark and drill four pilot holes for the Cable Bullet post mounting screws.
Before tightening the structural screws, plumb each post with shims, or use
the four 3/8” leveling set screws in post base (hard surfaces only). Once your
posts are secured, set the base cover plate in place.
STEP 2 | ATTACH YOUR TOP RAIL
On tensioning/end posts, use the adhesive strip to temporarily fix the post
top collar to your handrail at the desired location. Screw the collar to the
handrail,then reassemble the collar and center pin before tightening the set
screw. The intermediate post top can be angled for stair runs. Loosen the
screw that attaches the top to the post column, and adjust the angle as
needed.
STEP 3 | INSTALL YOUR CABLES
Your railing is now ready for cable infill.
Complete this process following the Tensioner Kit for Metal Posts setup guide.

tensioners to cover longer runs.

To minimize deflection under load, add intermediate posts, or cable spacer
bars every 42–48 inches.
