These collars are used in situations where a collar is put into place before the concrete is poured. Two styles are available either as a compact cast-in collar (B315LC) or with a high riser (B315HC). Unlike intumescent assisted mechanical damper type fire collars, Firepro B315 contain no fusible links or moving parts to require servicing. As the fire stopping intumescent material in our product is around the outside of the uninterrupted pipe it does not affect the performance of the pipe. Sizes up to and including 100mm provide 4 hour FRL, for up to 100mm internal diameter pipes and the 150mm collar 2 hour FRL (B315LC). View B315 Datasheet (pdf)
