SpecSeal BLU/BLU2 Metal Restraining Collar 25' Roll

The SpecSeal Metal Restraining Collar is for use with SpecSeal BLU/BLU2 Wrap Strips to allow for the collapse of non-metallic piping of up to 12" diameter.

SpecSeal Wrap Strips are highly flexible, elastomeric strips designed to firestop combustible penetrations in fire-rated floors, floor/ceilings, and walls. Convenient 12 ft (3.7 m) rolls, or individually sized strips facilitate installation and minimize waste.

These products utilize STI’s fast responding intumescent technology, providing very responsive and highly directionalized expansion. Rapid expansion provides quick closure for burning combustible penetrants.

When exposed to temperatures in excess of 250°F (121°C), the SpecSeal Wrap Strip begins to expand (intumesce) rapidly to form a dense, highly insulative char. Free expansion varies according to the grade utilized (See Table A). Expansion continues up to temperatures of 1,000°F (538°C).

• Rapid expansion - closes off burning penetrants faster
• High volume char - significant expansion seals off opening
• Water-resistant - no soluble or hygroscopic ingredients
• Economical - 12 ft (3.7 m) rolls or precut strips means no piecing, less waste
• Highly flexible - no foil, easier to install
• Versatile - performer for a wide range of complex applications

Applications

• Plastic Pipe

SpecSeal Wrap Strips are used for firestopping combustible penetrants such as nonmetallic pipes or pipe insulation. Installations were developed for both “tuck-in” applications (where strips are secured around the penetrant and slid into the opening) and restraining collar assemblies (for surface mounting). For larger openings or complex penetrant configurations, systems were developed utilizing wrap strips in conjunction with other SpecSeal products. SpecSeal Wrap Strips are suitable for use in all common forms of construction including concrete floors, concrete over steel deck, concrete walls, concrete block walls, gypsum board/stud walls, and wood floor/ceiling assemblies.

Specifications
