Matt Finish Collet Knobs (Style 1)

From Sifam, this selection of matt finish collet knobs are functional and simplistic. Compatible with various push-fit accessories, such as dial skirts and nut covers, this range of collet knobs are as versatile as they are practical.

Features and Benefits:

• Four diameters of collet knobs with a variety of collet sizes for different pot shafts etc
• The 21mm and 29mm versions incorporate an 8mm AF tightening nut and a recess in the base which will accommodate the control mounting nut
• The 11mm and 15mm versions incorporate round nuts with slots
• Fixing tools are available separately for tightening the collets, they do not have sufficient size to cover the control mounting nut and separate nut covers are available
