Cast-In Devices & Cable Pathways
Devices turn firestopping from a trade task into a detail that is simply already done. Cast-In-Place Devices (CIDs) nail to the deck form before the pour — when the concrete sets, the firestop is in place and plumbers just run pipe through. No coring, no sealant, no return trip.
Pass Thru Pro pathways do the same for cable: a re-enterable, self-sealing sleeve through rated walls that lets IT and low-voltage trades add or remove cables for the life of the building without ever re-firestopping. It is the direct alternative to STI EZ Path at meaningfully better pricing.
Both are UL Classified systems. On repetitive multi-story work, devices routinely cut firestopping labor by half or more — we will run the math against your penetration count and quote by the pallet.

Cast-In Devices & Cable Pathways — frequently asked
How do cast-in-place firestop devices save money?
A CID is placed in seconds on the deck form before the pour and needs no coring, sealing or later firestop visit. Across hundreds of penetrations on a multi-story pour, that is typically a 50%+ labor reduction versus core-and-seal.
Is Pass Thru Pro an alternative to STI EZ Path?
Yes — Pass Thru Pro is the Metacaulk re-enterable cable pathway: UL Classified through rated walls, self-sealing intumescent gaskets, zero maintenance as cables change. Contractors switch for availability and price; we ship same-day from NJ.
Do pathway devices need sealant too?
No — the device IS the listed system. Install per the UL listing and cables pass through the self-sealing pathway with no putty or caulk, and stay re-enterable forever.
Need the right UL system?
Send your penetration schedule or a photo — we match the UL Classified system, provide submittal documentation free, and ship same-day from New Jersey at distributor pricing.
