Middle Atlantic Adjustable Rung Drop w/Spools 12in. W Steel Black Zinc finish - CLH-ARD12

Middle Atlantic CLH-ARD12 Adjustable Rung Drop with Spools — 12 in. Cable Ladder Component

Overview

The CLH-ARD12 is a 12-inch-wide adjustable rung drop with integrated spools, designed for transitioning cables vertically within a cable ladder run. Where a fixed rung creates a hard bend that can kink or stress high-count fiber and copper bundles, the adjustable drop lets you dial in the correct descent angle and the spools provide a radius-controlled guide — protecting cable jacket integrity at the transition point. This component fits infrastructure installations where cable trays or ladders change elevation, such as above-ceiling-to-rack drops in structured cabling environments or cable management runs above server rows and patch panels.

Compatibility

The CLH-ARD12 is engineered for the Middle Atlantic CLH cable ladder system. It integrates with Middle Atlantic's CLH-series horizontal cable ladder sections and is sized to match the 12-inch runway width used throughout that product family. Verify your installed CLH runway width before ordering — Middle Atlantic offers equivalent rung drop components in other widths for wider runway configurations. Consult your cable ladder accessories selection to confirm cross-series fit before mixing components from different runway families.

Installation Notes

The adjustable rung mechanism allows the drop angle to be set during installation — position before final fastening to match the actual cable path. Spools are fixed to the rung and serve as bend-radius guides; route cables through or over the spools rather than bypassing them to preserve the cable protection function. Steel construction with black zinc finish suits indoor rack room and above-ceiling environments. Shipping weight is 3.2 lbs (1.5 kg); the 12-inch width (30.5 cm) governs fit to the mating ladder section — confirm runway width before installation.
