Yes. The SB81319LT6SL horizontal transition tray is 19 inches wide, which is the standard EIA rack mounting width, so it drops into a standard 19 inch open frame rack or cabinet. Depth into the rack is 6 inches and the tray is 1.5 inches tall, so it occupies a single rack unit of vertical space.

It is the handoff point between overhead or vertical cable routing and the equipment in the rack. Cable comes into the tray, gets supported and dressed across the 19 inch width, then breaks out to the gear. The SB81319LT6SL provides top and bottom adjustable cable support, so bundles can be retained above and below the tray rather than sagging against rack rails.

Aluminum with a silver powder coat finish. Aluminum keeps the weight down (5 lb) for a one-person install and avoids the rust risk of bare steel in a mechanical or telecom space, and the powder coat gives a painted surface that matches typical silver rack hardware rather than black.

No. The SB81319LT6SL is finished in silver powder coat. If your racks and ladder rack are black, this tray will stand out. For a black installation, specify the black-finish version of the B-Line horizontal transition tray instead of this silver one.

Six inches of depth. That is the tray's front-to-back dimension, so in a shallow open frame rack you need to confirm you have 6 inches clear at the mounting level without fouling patch panel bodies or PDU whips behind it. Vertical space needed is 1.5 inches.

The SB81319LT6SL is a passive aluminum cable support tray and no certification applies to it. If your submittal requires a listed pathway component, that requirement usually attaches to the ladder rack or raceway system it feeds, not to a rack mounted transition tray.
