P1000DS - 1-5/8" x 1-5/8", 12 Gage; with Double Slots

P1000DS-No-Dimensions.png

Unistrut's P1000DS (double slotted) is design for attachment on both the top and bottom of the channel. The DS slots allow attachment of pipe clamps and channel nuts so that both sides of the strut may be used.

This product is a good substitution for many back-to-back channels, offering similar functionality, and is great for pipe and conduit trapeze supports. Pipe and conduit may be supported on both the top and bottom sides.

Product dimensions are 1 5/8" wide x 1 5/8" tall x 12 ga. thick; with double slots. The slots are 7/8" wide x 2 3/4" long with in-turned lips and 3 1/2" on center. Standard lengths are 10 feet: 10' or 10’ 1/8" (3.05m) ± 1/8" (3 mm) and 20 feet: 20' or 20’ 3/8" (6.11m) ± 1/8" (3 mm) 1/8"

Our P1000DS is available in the following finishes: Pre-Galvanized (PG), Hot-Dip Galvanized (HG), Plain (PL) and Green (GR).
