P4000T – 1-5/8″ x 13/16″, 16 Gage, Slotted

Unistrut’s P4000T this channel is commonly used for trapeze supports, seismic bracing, ceiling grids, pipe, conduit, duct and cable tray supports, racks, and other general framing.  The slotted material allows for adjustability and doesn’t compromise too much on material strength. It has 85% of the capacity of the solid version of the profile.

Product dimensions are 1 5/8″ wide x 13/16″ tall x 16 ga. thick. Slots are sized for a 1/2″ threaded rod or fastener.

Our P4000T is available in Pre-Galvanized (PG), Unistrut Defender (DF), Hot-Dip Galvanized (HG), Plain (PL), Green (GR), Zinc Dichromate (ZD), Stainless Steel (SS or ST) and Aluminum (EA).
