4. Drill four boreholes into the concrete to the required embedment depth
using a hammer drill and 7/16" masonry drill bit. When drilling, check
periodically to ensure boreholes remain plumb and aligned with all four of
the concrete surface plate corner holes.
REqUIRED EMBEDMENT DEPTH FOR THREADED RODS:
TAM‑RAIL 38" Post Mount Kits: 3‑1/2"
TAM‑RAIL 44" Post Mount Kits: 4"
5. Properly clean all boreholes using a 7/16" round steel brush and
compressed air (see Hilti HIT‑RE 500‑SD Instructions, Steps 2‑4).
Boreholes must be free of dust, debris, ice, oil, grease and other
contaminants.
6. Prepare the HIT‑RE 500‑SD adhesive for use with a compatible
Hilti dispenser and discard initial adhesive (see Hilti HIT‑RE 500‑SD
Instructions, Steps 5‑8).
7. Inject adhesive into the boreholes without forming air voids, starting from
the bottom of each borehole and slowly withdrawing the dispenser. Fill
holes approximately 2/3 full or as required to ensure that the annular
gap between the threaded rod and concrete is completely filled (see Hilti
HIT‑RE 500‑SD Instructions, Steps 9‑10).
8. Insert the supplied threaded rods into the boreholes to the required depth,
slowly twisting the rods as they are inserted (see Hilti HIT‑RE 500‑SD
Instructions, Steps 11‑13). Remove excess epoxy above the boreholes and
ensure that the mounting surface remains clear of debris.
IMPORTANT: Once installed correctly, do not disturb the threaded
rods until the appropriate setting time has elapsed. Do not install the
post mount or apply load to the concrete anchors until the adhesive
is fully cured. Follow the adhesive setting guidelines published in the
Hilti HIT‑RE 500‑SD Instructions.
9. After the concrete anchors are fully cured, carefully position the post
mount over the threaded rods and install flush onto the concrete surface.
10. Install four of the supplied stainless steel
washers and nuts over the threaded rods
and tighten nuts to 15 ft‑lb using a torque
wrench.
11. Check the post with a level. If the post needs
to be adjusted for plumb install four of the
supplied 1" leveling bolts. (Fig. 3) Adjust
the leveling bolts until post is plumb and all
four leveling bolts are in contact with the
concrete surface plate.
NOTE: It may be necessary to slightly loosen
the coated hex nuts to allow the post mount
member to be adjusted.
Do not adjust
the stainless steel hex nuts used for
concrete anchoring. When post is level,
reapply 33 ft‑lb torque on coated hex nuts.
12. Install the post ring over the concrete surface plate.

may need to be removed for proper post ring fit. If required, carefully trim
the threaded rods ensuring that a minimum of three threads remain above
each of the stainless steel nuts. (Fig. 4) Recheck and reapply the required
torque on each of the hex nuts.
13. Install the two guide blocks onto the post mount member (Fig. 5).
Position the lower guide block at the bottom of the post and secure in
place by installing one of the supplied self‑drilling screws through the
center of the guide block and into the post until firmly seated.
Position the upper guide block so that the top of the guide block is 1"
above the top of the post member and secure in place by installing one of
the supplied self‑drilling screws through the center of the guide block and
into the post until firmly seated.
14. Trim the TAM‑RAIL post sleeve to the desired length and install over the
post mount.
15. Apply PVC glue (not provided) to the post cap and install over the top of the
post sleeve.
To install a TAM‑RAIL Straight or Stair Rail Kit to the TAM‑RAIL Post Mount,
use the 1" screws provided in this kit. Refer to the TAM‑RAIL Straight or
Stair Rail Installation Instructions for details.
