TQB Free Breathing Aerial Closure 3M SLIC-3.6X33
3M SLiC Free-breathing Aerial Closure
Free-Breathing Design
Allows pressure equalization with the environment, minimizing condensation and simplifying maintenance.One-Piece Construction
Enables full splice access without removing the closure from the cable—saving labor and reducing service time.Versatile Mounting
Ideal for strand-mount aerial applications, including in-line, butt, or taut sheath splicing with single or ribbon cable.Durable & Weather-Resistant
The double-walled, blow-molded body resists impact, cracking, and environmental stress—even in extreme weather conditions.
3M’s SLiC Fiber Aerial Closures are high-performance, free-breathing mechanical closures engineered for cost-effective aerial fiber deployment in access networks such as FTTN, HFC, and FTTP. Designed for both new construction and maintenance, these closures are widely used by service providers for telecom copper cable jointing and splicing protection in aerial environments.
Tianyulink TQB Aerial Closure — 3M™ SLiC™ Compatible Copper Splice Solution
Tianyulink’s TQB Aerial Closure is a free-breathing, strand-mount aerial enclosure designed as a high-quality, cost-effective alternative to the 3M™ SLiC™ Aerial Closure. Tailored for non-pressurized copper cable splicing, the TQB is ideal for straight, butt, and branch splices in aerial network installations.
The one-piece construction allows full splice access without removing the closure or requiring cable bonding—simplifying both installation and re-entry.
The closure body features a lightweight, double-walled, blow-molded housing, made from UV- and weather-resistant plastic. Built to withstand extreme conditions, it resists cracking and degradation, offering long-term durability and protection.
