Stainless Steel Insulation Dome Caps


Stainless steel insulation dome caps are used in conjunction with weld pins, insulation hangers and lacing anchors to cover the sharp pin ends and hold them in place. The finish will often match the insulation material that is being used.

These stainless steel insulation dome caps have a shiny surface that appears unfinished in appearance adding a nice touch to any application. Please review our other selection of dome caps that are available in an aluminum finish.
