3" x 3" Internal Snap-in End Caps - TEXTURED Matte Black Surface - Fits 11 - 14 Gauge

These caps have flexible fins that will accommodate both 11 gauge or 14 gauge wall thicknesses (.120" to .075" wall thicknesses).

With some handy work, you may trim the fins so that this cap will fit 7 gauge (.188") wall tube. However the corners on the cap may not be a good match to the tube because a 7 gauge wall tube will have more rounding in the corners vs. an 11 gauge tube.

Once these caps are installed, they will not be removed easily
