Introducing the ProX XT-BP12ASPSTX2 Pair of 12" Aluminum 6mm Truss Top Plates with 1 3/8" Speaker Stud Mounts. When you cap a truss tower with a PA speaker, a moving head or other lighting, the top plate is the part holding everything together, and it has to be solid every time. This set gives you two matching 12" x 12" aluminum top plates, two 1 3/8" speaker mounting studs and the connecting hardware, so you can finish a left and right pair of totems in one order. Built for F34, F32 and F31 conical square truss, the ProX BP12 is a clean, simple way to get speakers and fixtures up on the truss you already own.

Solid 12" x 12" Aluminum Plate Each plate measures 12" x 12" and is made from 6mm (about 1/4") thick aluminum. That gives you a stiff, flat platform that still stays light enough to carry from the truck to the stage without a second trip. The edges are smooth and rounded, so they are easier on hands, cables and soft goods during load in and load out.

1 3/8" Speaker Stud Mount An offset hole on each plate accepts the included ProX XT-SPST 1 3/8" Speaker Mounting Stud. 1 3/8" is the common pole mount size on a lot of PA speakers, so you can set a speaker right on top of your truss tower and get it up over the crowd. The same stud setup also works for moving heads and other lighting, which means one pair of plates can serve your audio rig one night and your lighting rig the next.

Cable Routing Pass Through A larger offset hole lets you run power and signal cables up through the plate. This keeps your cable path tidy and out of sight, which looks more professional in front of an audience and helps keep loose cables from getting snagged or pulled during the show.

CNC Machined Slots and Center Mounting Hole CNC machined slots near the edges and a mounting hole at the center give you more ways to connect each plate to your truss and other compatible gear. Clean, precise cuts mean the hardware lines up the way it should when you are working against the clock.

Fits F34, F32 and F31 Conical Square Truss These plates are made for F34, F32 and F31 conical square truss. ProX uses industry standard dimensions, so the plates are also compatible with most other truss brands. That is a big help if your inventory is a mix of truss picked up over the years.

Connecting Hardware Included The pair ships with both speaker studs and a connecting hardware set, so you can attach the plates to your truss right out of the box without placing a separate hardware order.

Keep Them Protected Between Gigs To keep your plates clean, organized and scratch free on the road, pair them with the ProX XB-BP12TB Universal Gig Bag, made to fit 12" top and base plates.
