4" x 4" Internal Snap-in End Caps - TEXTURED Matte Black Surface - Fits 7 - 11 Gauge

These caps have flexible fins that will accommodate both 7 gauge or 11 gauge wall thicknesses (.188" to .120" wall thicknesses).

While these caps will snap into 7 gauge tubing, the corner radius on the cap may not be an identical match to corner radius of the tube because a 7 gauge wall tube will have more rounded corners (larger radius) vs. an 11 gauge tube.

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