Metallics CTAH11S 11 Air Handling Cbl Tie Std Ny

The Metallics CTAH11S is an air handling (plenum rated) cable tie, 11 inches, standard cross section, made of nylon. Air handling ties are the ones specified for bundling cable in a plenum or return air space, where ordinary ties are not accepted. If your runs sit above a lay-in ceiling used as a return air path, this is the tie class you want rather than a general purpose nylon tie.

At 11 inches of overall strap length, the CTAH11S wraps a mid size bundle, the common size electricians reach for on branch circuit and low voltage bundles rather than single cables. Length is the strap length, not the bundle diameter, so allow for the head and the tail you pull through when you size it to your bundle.

Standard cross section, in nylon. That is the general purpose strap thickness, fine for cable bundling and routing support. For bundles that carry real weight or for outdoor and UV exposed runs, step up to a heavy duty strap or a weather resistant black nylon tie instead.

Electrical supply item used for bundling and dressing conductors, MC cable, and low voltage runs. The air handling rating is the reason to pick it: it is the version intended for cable in plenum spaces, so one tie type can cover both plenum and non plenum runs on the same job instead of stocking two.
