Middle Atlantic 90 Vert. Outside Ladder Bend 18IN W - CLB-VO90-W18

Middle Atlantic CLB-VO90-W18 90° Vertical Outside Cable Ladder Bend, 18 In Wide

Overview

The Middle Atlantic CLB-VO90-W18 is an 18-inch-wide vertical outside 90-degree bend section for Middle Atlantic's Middle Atlantic cable ladder system. It solves a specific routing problem: when a horizontal cable ladder run needs to drop vertically at an outside corner — such as transitioning from an overhead tray to a wall-mounted rack section — this fitting maintains the ladder's open tray geometry through the turn without kinking cables or forcing sharp bends that degrade high-strand-count copper and fiber runs.

The CLB-VO90-W18 ships as a single unit and connects inline with standard CLB ladder sections. At 18 inches wide, it accommodates the same bundle capacity as the ladder run it terminates, so there's no bottleneck at the transition point. The 15.5-inch developed length gives you a controlled, gradual radius through the 90-degree turn rather than a tight elbow — important for maintaining bend-radius compliance on category-rated copper and OM-series fiber.

Key Features

• 18-inch tray width: Matches full-width CLB ladder sections end-to-end — no reduction in usable cable space through the bend, which matters when you're routing dense copper bundles or parallel fiber runs in a network infrastructure installation.
• Vertical outside geometry: Designed specifically for outside corners where the cable run transitions from horizontal overhead routing down a wall face. Using the wrong bend type (inside vs. outside) here forces cables to the short radius — this fitting keeps them on the long radius where bend-radius specs are met.
• 15.5-inch developed length: The sweep through the 90-degree turn spans 15.5 inches, providing a gradual arc rather than a tight elbow. This is the critical dimension for fiber installations where minimum bend radius is a hard limit.
• 6 lb shipping weight: Finished unit is lightweight enough for overhead mounting without adding meaningful structural load to the supporting infrastructure.
• Single-unit package: Ships as one piece — no assembly or sub-component count to track on the job site.

Integration and Compatibility

The CLB-VO90-W18 (often searched as CLB VO90 W18) is designed for use within the Middle Atlantic CLB cable ladder product family. Verify that your straight ladder sections share the 18-inch width designation before ordering — CLB ladder fittings are width-matched and the 18-inch bend will not align correctly with 12-inch or 24-inch ladder sections. Pair with compatible rack and enclosure infrastructure for a complete structured cabling pathway. TAA compliance is not applicable to this component.

Frequently Asked Questions

Q: What is the difference between a vertical outside bend and a vertical inside bend?

A: A vertical outside bend (this fitting) routes cables around the exterior of a corner — the cables travel the longer arc. A vertical inside bend routes cables around the interior of a corner where the arc is shorter. For most cable-heavy runs, the outside bend is preferred because it maintains a larger bend radius, which is critical for fiber and category-rated copper.

Q: Will the CLB-VO90-W18 connect directly to standard CLB straight ladder sections?

A: Yes — it is designed as an inline fitting for the Middle Atlantic CLB cable ladder system. Confirm that your straight sections are also 18 inches wide, as CLB fittings are width-matched.

Q: Is the CLB-VO90-W18 TAA compliant?

A: No. Per manufacturer data, TAA compliance is not applicable to this component.

Q: How many units come in one package?

A: One unit per package (package count: 1).

Q: What is the developed length through the bend?

A: The developed (sweep) length is 15.5 inches, providing a gradual 90-degree turn suited to bend-radius-sensitive cable types including OM-series fiber and category-rated copper.

Ted Perry

The CLB-VO90-W18 is the component most integrators forget to spec until they're on the ladder trying to force cables around a corner — at which point you're either ordering overnight or improvising with zip-ties and prayer. The 15.5-inch developed length is the number that matters here: it's what keeps you inside minimum bend radius on OM3/OM4 fiber and 10GBase-T copper without calculating sweep geometry by hand on-site.

Technical Highlights:

• 18-inch tray width: Matches the full width of standard CLB ladder sections — no cable bundle compression through the turn, which can be a failure point on high-density runs carrying 40+ cables.
• 15.5-inch developed length: The graduated arc through the 90-degree turn is long enough to satisfy manufacturer minimum bend radius requirements for OM-series multimode fiber without supplemental guides.
• 6 lb shipping weight: Lightweight steel construction means overhead installations don't require additional strut support at the bend point — it won't exceed the load rating of a standard CLB support span.

Deployment Considerations:

• Width-matching is non-negotiable: the CLB-VO90-W18 is an 18-inch fitting and will not align flush with 12-inch or 24-inch CLB sections — verify your straight-run width before the truck leaves the warehouse.
• Outside bend vs. inside bend selection is determined by which side of the corner the cable tray is on — get this wrong and your cables ride the short radius through the turn, potentially violating Category 6A or fiber bend specs.

This fitting is the right call on any structured cabling project where a CLB overhead ladder system needs to transition to a vertical wall drop — specifically in data center cage builds, IDF-to-MDF home-run pathways, and security system head-end rooms where cable management is part of the permanent infrastructure record.
