The Extron Captive Cable Pass-Through Kits provide modules with split-ring holes for AV cables. The unique, flexible split-ring design allows for ease of assembly, installation, and service. The Half-size module features two openings, and the Full-size module has four openings. Each opening is 0.375” (0.95 cm) in diameter to accommodate most AV cable sizes. Hole plugs are included to cover any unused openings. Each module in the kit mounts in products that accept Flex55 modules, such as SMB 210 and EWB 210 mounting boxes and the Cable Cubby F55 Edge enclosure. The Captive Cable Pass-Through Kits are available in black and white.
