Box of 500 Super Staples. Used to hold pex tube down to foam board. These are aggressive staples and will not let the tube float up during concrete pour.
Works best in 1.5 and thicker foam board.
These staples will work in most guns with some adjusting of the retainer screw.
Works with either 1/2" ID (5/8" OD) or 5/8" ID (3/4"OD) pex tube.
