Original Dunlop offset grommets (i.e. rubber bumpers) used on the underside of the treadle piece (rocking structure) of wah pedal enclosures. Made in USA. Set of 12 (3x4) bumpers includes:

• 3 pieces measuring about 0.38" diameter x 0.35" height (with 0.13" diameter center hole)
• 3 pieces measuring about 0.38" diameter x 0.21" height (no hole)
• 3 pieces measuring about 0.38" diameter x 0.16" height (no hole)
• 3 pieces measuring about 0.38" diameter x 0.13" height (no hole)

Commonly, two front bumpers are fastened underneath the toe-end of the treadle and one rear bumper is fastened underneath the heel-end of the treadle. Alternate bumper heights allow you to customize the fit and feel when stepping into the footswitch or rocking back to a maximum open treadle position. Remove the old bumper(s), clean the area(s) underneath the treadle where you would like to place each new bumper and fasten using contact cement or other pliable adhesive.
