CABLE PLACEMENT
The diagram and inserts below identify the placement and
proper way to attach the cable assemblies to the building.
1. Attach the first cable assembly at the bottom of the
center post using a band clamp as shown in drawing A.
2. Move to the top of the first interior rafter and wrap the
loose end of cable over the top of the upper purlin and
back under the purlin. Attach the remaining section of
the cable assembly using a cable thimble and two (2)
cable clamps. (See Drawing B).
NOTE:
No turnbuckle is needed; only one (1)
turnbuckle is used for each assembly.
3. Secure the band clamp to the center post frame using
Tek screws.
4. Repeat the same procedures for the remaining
cable installation.
