This new Heavy Duty Max mounting strip material is a new polymer with higher tinsel strength more than the high density (HDPE). This material reduces stretch and makes for a stronger strip. It comes in 1" (approx spacing .98"), 3" (approx). The standard rolls are available in 200', 500', and 1000' rolls. These can be used with the MISR clips, you just fold over the top hole and zip tie. These do not have the small zip tie holes since it is not needed with this material, only the strips have this feature. Also these can't be used with the strip material.
This material comes in Black or Frosted. Be sure to select color!
