CommScope SEC-412 (2-Pack) SnapSeal Entry Cushion 1/2in Coaxial 4-Port

The CommScope Andrew SEC-412 SnapSeal™ Entry Cushion is a purpose-engineered, tool-free cable sealing solution for 4-inch port entrance panels used in wireless base station and distributed antenna system (DAS) installations. Molded from thermoplastic elastomer (TPE), the cushion compresses around up to four 1/2-inch corrugated coaxial cables simultaneously, creating a reliable environmental seal at the tower or shelter cable entry point. Each unit ships with the SnapSeal entry cushion and a compression ring, providing everything required for a secure, repeatable installation without adhesives or supplemental sealing compounds. Designed for CommScope's HELIAX family of 1/2-inch corrugated coaxial cables, the SEC-412 is an ideal choice wherever multiple feeder cables must penetrate a common 4-inch entry panel port in a weather-tight manner.

Key features & benefits

• 4-Cable Simultaneous Entry — A single SEC-412 cushion accommodates four 1/2-inch corrugated coaxial cables through one 4-inch port, maximizing cable density while minimizing the number of entry points required on a shelter or equipment room wall.
• SnapSeal Compression-Ring Design — The included compression ring locks the TPE cushion into the port panel, delivering a consistent, repeatable environmental seal around each cable without tools, adhesives, or additional sealing materials.
• Thermoplastic Elastomer (TPE) Construction — The cushion body is manufactured from TPE, a material that combines the flexibility of rubber with the processability of thermoplastics, ensuring a conforming seal around the corrugated cable jacket over a wide range of environmental conditions.
• Corrugated Cable Compatibility — Sized specifically for 1/2-inch corrugated coaxial cable, the SEC-412 is confirmed compatible with the full CommScope HELIAX 1/2-inch corrugated cable portfolio, including LDF4-50A, FSJ4-50B, AL4RPV-50, and HL4RPV-50 variants.
• Complete Kit in a Single SKU — Each SEC-412 package contains both the SnapSeal entry cushion and the compression ring, so installers receive a ready-to-deploy assembly without sourcing secondary hardware.
• Sold as a 2-Pack on This Listing — This listing provides two (2) SEC-412 units, offering immediate spares or simultaneous installation at multiple entry points, reducing procurement lead time on multi-sector or multi-carrier tower builds.
