CRL TPR Glazing Setting Blocks 1/8 x 1 x 4 in

• Compatible with silicone, butyl, polyurethane, and polysulfide sealants
• UV stabilized thermoplastic rubber

CRL Thermoplastic Rubber (TPR) Setting Blocks (SKU: TPR576) are 90 durometer TPR glazing blocks engineered as a direct alternative to neoprene setting blocks. Ideal for structural glazing and curtain wall applications, these setting blocks offer excellent chemical resistance, will not mar or stain surfaces, and are available in the most popular neoprene block sizes. Use with modern structural glazing sealants and other common sealant chemistries; job-specific compatibility testing with your chosen silicone sealant manufacturer is recommended.

Product Warning:

To ensure sealant-to-block compatibility, silicone sealant manufacturers can test accessory materials per ASTM C1087-87. Written test results are provided; testing typically requires about four weeks from receipt of samples.
