High-Resiliency Couplers Help You Create Custom Cable Management SchemesThe SmartRack® SRWBUNVCPLR includes 50 black powder-coated metal couplers, each with an M6 flange nut and M6 x 20 carriage bolt for easy installation with your wire mesh cable tray. By creating a secure connection point between two intersecting sections of cable tray in your server room or data center, these couplers help you create sweeps and 90-degree intersections that guide the direction of cabling to your liking.
