T-STRIP PROCEDURE
After the H-strip is in place, the T-strip is installed in the intermittent slots.
Step 1:
Position the T-strip such that one end is located at the center of one of the slots. Then apply hand pressure to force the teeth into position and slide the T-strip to the end of the slot ( g. 1, g. 2 and g. 3).
Step 2:
Apply hand pressure on the T-strip starting at the installed end of the slot and work towards the other end forcing the T-strip’s teeth into the slot as
you go. Then at the other end of the slot, cut the T-strip to the correct length. Continue this procedure for the other slots ( g. 4 and g. 5).
Note:
To economize on T-strip material, two short sections of T-strip may be used to seal a slot instead of one continuous section. Again, duct tape
can be applied at the butt-joint of the T-strip.
As a nal operation (optional), to ensure system rigidity and to lock
the sealing strips into position, use tie wraps or the Repair Kit (#40-0174). Tie wraps are inserted at the midpoint of each of the
intermittent slots ( g. 6)
This conduit length is now completed and work can begin on the next length. When installing subsequent conduit lengths, ensure that they are oriented properly such that a bell end and a spigot end are facing each other for every set of adjacent conduits. As subsequent conduits are completed with the installation of H & T-strips, they can be coupled in
bell & spigot fashion. Since tight mechanical sealing is not possible at the bell and spigot joint, taping or additional tie wraps can be used to ensure better joint integrity.
