Velcro - Industrial Strength holds up to 10lbs. Very strong hold. Includes both hook and loop sides.
2 inches wide and sold by the inch.
Quantity 1 will get you a 2" wide, 1" long piece. One of these at the top of the pedal and another at the bottom is usually plenty strong to hold a typical Boss, Ibanez, MXR, etc. pedal.
Quantity 4 will get you a 2" wide, 4" long piece.
We try and supply you with a continuous piece but that's not always possible. Orders of 1" will be a single piece always.
