CAP Type (Waterproof)

Folding Bulb Type blind rivets have three folded legs on the blind side. This special design provides high clamp load and is ideal for fastening soft materials. Folding Bulb Type blind rivets stand up to the rigors of installation and long-term use because of resistant to weather and tampering. Ideal for metal roof attachments, facade panel to metal, and back-fastening of IMP panels.
