To achieve this alignment, multiple mounting holes and slots are provided. The hanger cradle has three sets of U-bolt mounting slots. The cradle and brace have two staggered rows of slots for mounting to the support and the support beam has two corresponding mounting holes.

Alternate mounting hole positions are also provided as described in the CAUTION statement in Step 3. The general procedure is:

  1. With the cable setting in the cradles at low levels, or the cable nesting against the cradles at high level, visually determine which corrugation will be used to secure the cable to the hanger.

  2. Before inserting the U-bolt into the hanger, wrap emery cloth (#220310) around the dowel rod (220311) and remove the paint from the bottom of this corrugation over a length of 6 inches (153 mm). The 6-inch (153 mm) length should be along that part of the corrugation that will contact the curved section of the U-bolt. This contact grounds the cable at the support. Apply a coating of Alumashield® (#203233-4) over the entire area where paint was removed.

  3. Install the U-bolt around this corrugation and adjust the cradle/brace, within their corresponding elongated slots, to obtain alignment between the U-bolt and the U-bolt mounting slots. If these adjustments are not sufficient, then reattach the cradle/brace to the support in the adjacent slot of the alternate row that moves the U-bolt closer to a set of mounting slots. The staggering of the slots is designed to then obtain alignment of the U-bolt and the mounting slots through adjustments within the elongated slots. Once aligned, tighten the cradle, brace, and clamping plates to the support.

CAUTION: Never assemble a hanger with the cable flange against the cradle. Use the additional mounting slots in the cradle/brace or the alternate mounting positions on the support beam to avoid these occurences. The illustration shows the extreme positioning that is possible for a high-level support hanger. For low-level supports, an extension bracket is provided to obtain a smiliar range for the hanger position.
4. Tighten the U-bolt gradually, alternating between the ends, to seat it into the corrugation and avoid damage to the outer conductor. Tighten until completely seated against the staked nuts on the U-bolt. Cost the exposed threaded ends of the U-bolt with Alumashield® (#203233-4).



CAUTION: Proper grounding requires good contact between the U-bolt and the corrugation surface where the paint was removed.
