Middle Atlantic CLH-ARD12 – Adjustable Rung Cable Drop with Spools

Product Overview

The Middle Atlantic CLH-ARD12 is an adjustable rung cable drop with spools designed for 12-inch-wide cable ladder runs. It combines a steel ladder rung, an aluminum cable drop, and three plastic spools into a single cable ladder accessory that guides cabling off the ladder while protecting bend radius. Because the rung position is adjustable, the CLH-ARD12 works on both new cable ladder builds and existing installations. It is compatible with most popular ladder brands and accessories, making it an easy retrofit for mixed-vendor pathways.

Product Description

Managing vertical cable transitions is one of the most common failure points in rack room cable management. Where bundles leave a horizontal ladder run and drop toward racks or wall fields, unsupported cable can sag, kink, or violate minimum bend radius—degrading category cabling and fiber performance. The Middle Atlantic CLH-ARD12 adjustable rung cable drop addresses this transition point directly. The rung itself is steel with a black zinc finish, providing a rigid mounting point across the 12-inch ladder width. The attached cable drop is aluminum with a black powder coat finish, creating a smooth, radiused exit path for descending bundles. Three black plastic spools give installers defined positions to dress and segregate cable groups as they leave the ladder. Because the assembly adjusts along the ladder, integrators can place the drop exactly where the bundle needs to exit rather than where a fixed rung happens to land. The CLH-ARD12 is the 12-inch model in the series; 18-inch (CLH-ARD18) and 24-inch (CLH-ARD24) versions are available as variants on this listing for wider ladder runs. All three share the same construction and finish, so a facility can standardize its cable ladder accessories across different pathway widths.

Key Features

• Bend Radius Protection — The radiused aluminum drop guides cable off the ladder without kinks, protecting bend radius on copper and fiber bundles.
• Steel Rung Construction — The rung is steel with a black zinc finish for a rigid, durable mounting point across the ladder.
• Aluminum Cable Drop — The drop section is aluminum with a black powder coat finish that matches typical rack room hardware.
• Three Cable Spools — Black plastic spools let installers dress, route, and segregate bundles at the exit point.
• Adjustable Positioning — The rung drop adjusts along the ladder so the cable exit lands exactly where the design requires.
• Broad Compatibility — Works with most popular cable ladder brands and accessories, on both new and existing installations.
