MASON Spindle Pins

Insulation Pins / Spindle Pins are used to mechanically fix and install insulation material that can be pierced by metal spindles. To be used jointly with plastic button washers, as in the case of the existing hard copper pins.

Non-stick type with Resin (Japan) or Self-Adhesive Type.

MASON Insulation Pin / Spindle Pin is either stud-weldable, or designed to be bonded with adhesive for non-welded systems. Non-weldable pins are designed with the spindle mounted to a solid metal base.

The metal base is available with a ready-to-use ‘peel and stick’ backing, or a perforated base to be bonded with suitable adhesive. A self locking washer is applied over the protruding spindle to retain the insulation.
