3M - Fire Barrier Pass-Thru Device Square

SKU: PT4SD

​​​​​​​Description:

3M Fire Barrier Pass-Through Device Square is a one-piece hinged metal enclosure designed to prevent the passage of fire, smoke, and toxic gas. This easily installed device is ideal for firestopping penetrations in high-traffic areas where telecom, data, or electrical cables are frequently added or removed. Intumescent material and foam smoke seals achieve a 3-hour fire protection rating.

Features (From 3M Website):

  • Cable management solution for electrical, data, and communication applications
  • One-piece, square-hinged metal enclosure makes installation fast and easy
  • Intumescent material and foam smoke seals provide lasting firestop protection
  • Square shape allows for stacking multiple boxes for ganging
  • Re-enterable for high traffic areas or blank penetrations
  • Firestop tested for up to 3 hours in accordance with ASTM E 814 (UL 1479)

Applications (From 3M Website):

  • ​​​​​​​​​​​​​​Cables — 750 kcmil, Cat 6, fiber optic, 300 pair No. 24 AWG copper telephone cable, thermostat
  • Plastic pipes — ccPVC, PVC, ENT, CPVC, FRPP, PVDF, ccABS, ABS, rigid non-metallic, PEX
  • Metal pipes — copper, steel, iron, flexible gas
  • Insulated — AB/PVC on copper line sets
  • Combinations — metallic, non-metallic, and insulated pipes plus cables
  • Blank penetrations

​​​​​​​Positioning:

  • Cable management solution for electrical, data, and communication applications

Advantages:

  • A self-sealing pathway to compete with EZ-Path
  • Some tested systems include pipes as well as cables

Disadvantages:

  • No ESR - No report from a Nationally Recognized Third-party Laboratory confirming the product is Maintenance Free, whereas EZ-Path is Inspection and Maintenance Free.
  • No Custom Colors - There is no option for custom coloring at this time.
    • Many customers of EZ-Path take advantage of this feature to color-code their pathway based on usage
  • No Extension Modules - There is no ability to offer extension modules to accommodate thicker wall/floor assemblies.
  • No Radius Control Module - There is no ability to offer a Radius Control Accessory. Although not impacting fire performance, this design consideration is considered an advantage by low-voltage contractors and designers.
  • No Smoke & Acoustical Version - No capacity equivalent Smoke & Acoustical offering compromising the design of the overall cable pathway.
  • No posted ASTM E90 STC Testing - No posted achievable STC Rating.
    • All Fire-rated and Smoke & Acoustical EZ-Path Devices have STC Testing with results available upon request.
  • Fewer sizes and configurations are available.
