Plastic Washers for Rigid Insulation
Plastic washers resist moisture, chemicals, and friction and are good electrical insulators. These have a large surface that distributes holding pressure to reduce the likelihood of crushing insulation.
Washers with prongs enable pre-spotting into insulation for easy on-the-wall fastener assembly.
Washers with an insulating seal have a stiff center with a flexible perimeter that creates a barrier against air and moisture penetration when fastened to rigid insulation.

Pipe Dusters
This uniquely shaped brush wraps around overhead pipes and other curved surfaces to remove dust and dirt. For extended reach, attach one of the optional telescoping poles (sold separately).
Snap-In Fabric Grommets
No setting tools needed—snap the two parts together in a hole you've already cut to strengthen the hole and eliminate fraying. Use these grommets in tarps, covers, curtains, and other material. Trade size refers to the grommet’s hole size once set. Made of plastic, these grommets are chemical resistant and won't dry out and become brittle when exposed to UV rays. They can be used outdoors. Cutting punches are sold separately.
