Middle Atlantic 90 Degree Turn Hdwr 1PR - CLH-90T

Middle Atlantic CLH-90T Cable Ladder 90-Degree Turn Hardware Kit

Overview

The Middle Atlantic CLH-90T is a 90-degree turn splice kit designed for use with Middle Atlantic cable ladder systems. When a cable run needs to change direction — rounding a corner in a ceiling plenum, turning along a wall, or navigating around a structural obstruction — this hardware pair provides the mechanical connection point. Rather than improvising with field-cut bracket stock or relying on unsupported cable bends, the CLH-90T gives integrators a purpose-built, factory-finished fitting that maintains the ladder system's structural continuity through the turn. It ships as one pair (1 PR) and is compact enough to stage and install in tight above-ceiling spaces.

Key Features

• Purpose-built 90-degree turn geometry: Designed specifically for directional changes in Middle Atlantic cable management ladder runs — eliminates improvised field bends that stress cable jackets and create future maintenance headaches in structured cabling environments.
• Black zinc coat finish: The zinc coating provides corrosion resistance in the plenum and above-ceiling environments where cable ladders typically run. The black finish reduces visual contrast against dark ceiling spaces, which matters in exposed-ceiling architectural installations where aesthetics count.
• Compact footprint (2.13" W × 4.32" H × 2.9" D): At under 3 inches deep, the CLH-90T fits into constrained plenum and above-ceiling spaces without requiring you to clear additional clearance for the fitting itself. Stage it before the run reaches the corner to avoid awkward overhead assembly.
• Ships as one pair (1 PR): Each CLH-90T unit contains the hardware for one 90-degree turn — plan your cable ladder layout and count directional changes before ordering so you have the right quantity on hand for the full run.
• Shipping weight of 1.8 lbs: Lightweight construction means the fitting adds negligible load to the cable ladder span, which matters on longer unsupported runs where cumulative hardware weight can affect sag calculations.
• Integrates with Middle Atlantic cable ladder infrastructure: Part of the broader Middle Atlantic cable ladder accessory line — designed to splice and connect within that system's dimensional standards, not a generic fitting adapted from another product family.

Integration & Compatibility

The CLH-90T is a component within the Middle Atlantic cable ladder product family. It is intended for use with compatible Middle Atlantic cable ladder sections. Verify ladder width compatibility before ordering — cable ladder systems come in multiple widths, and the turn hardware must match the ladder width in use on your project. This fitting is not TAA compliant, which is a disqualifier for federal government installations subject to the Trade Agreements Act. For commercial, enterprise, and private-sector structured cabling deployments, TAA status is typically not a constraint.

Frequently Asked Questions

Q: Is the CLH-90T TAA compliant?

A: No. The CLH-90T is not TAA compliant. Federal installations requiring TAA-compliant cable management hardware should source an alternative fitting that meets those requirements.

Q: What finish does the CLH-90T use, and does it hold up in plenum environments?

A: The CLH-90T uses a black zinc coat finish, which provides corrosion resistance appropriate for typical above-ceiling and plenum cable ladder installations.

Q: How many 90-degree turns does one CLH-90T cover?

A: One CLH-90T unit provides the hardware for one 90-degree turn (sold as one pair). Count the number of directional changes in your cable ladder run and order accordingly.

Q: What are the physical dimensions of the CLH-90T?

A: The CLH-90T measures 2.13 inches wide, 4.32 inches tall, and 2.9 inches deep (5.4 cm × 11 cm × 7.4 cm). Shipping weight is 1.8 lbs (0.8 kg).

Q: Is the CLH-90T compatible with all Middle Atlantic cable ladder widths?

A: The CLH-90T is designed for the Middle Atlantic cable ladder system. Confirm the specific ladder width compatibility with the Middle Atlantic product documentation for your ladder series before ordering.

The CLH-90T is one of those fittings that seems minor until you're 20 feet up on a lift trying to make a cable ladder turn work with improvised hardware. At 2.9 inches deep and 1.8 lbs shipping weight, it is genuinely compact and light enough to pre-stage on the ladder before the lift goes up — which is how I'd always approach it on a multi-turn ceiling run.

Technical Highlights:

• Black zinc coat finish: Zinc coating handles the moisture and temperature swings typical of plenum and mechanical room environments — not a cosmetic choice, it's the right material call for above-ceiling installs that won't be re-accessed for years.
• Compact geometry (2.13" W × 2.9" D): Fits into tight plenum corridors without requiring you to engineer around the fitting itself. On dense above-ceiling runs with multiple conduit, HVAC, and cable tray conflicts, every inch of clearance matters.
• One pair per turn: Sold as 1 PR — straightforward to quantity-take-off from your ladder layout drawing. No ambiguity about what you're getting per unit.

Deployment Considerations:

• Verify ladder width compatibility before the CLH-90T arrives on site — Middle Atlantic cable ladder sections come in multiple widths, and the wrong turn hardware will not fit without modification.
• TAA non-compliance is a hard stop for federal and GSA projects. Flag this early in the spec review if your project has government procurement requirements, not after the hardware is on site.

The CLH-90T is the right call for commercial integrators running structured cable ladder systems through multi-turn ceiling paths in office buildouts, data rooms, or security head-end closets — where a factory-finished, properly dimensioned turn fitting keeps the installation looking professional and performing long-term.
