Middle Atlantic Blank END Fitting - AL3310B

Middle Atlantic AL3310B Blank End Fitting

Overview

The Middle Atlantic AL3310B is a 1-channel raceway blank end fitting sized 2-7/8 x 1-13/16 inches, machined from aluminum and finished in satin anodize. This accessory closes off the end of surface-mounted cable raceways in surveillance installations, network closets, and other environments where cable management and professional appearance matter. The AL3310B pairs with compatible Wiremold and Middle Atlantic raceway systems to provide a clean termination point and prevent dust, pest ingress, and accidental cable snag at raceway ends.

Key Features

• Aluminum construction: Non-ferrous material resists corrosion in damp server rooms, outdoor-adjacent cable runs, and coastal environments — reduces maintenance and discoloration compared to steel fittings.
• Satin anodized finish: Provides a unified aesthetic across modern installations and hides fingerprints better than polished finishes — matters when the raceway is visible above suspended ceilings or in client-facing mechanical spaces.
• 1-channel design: Fits standard single-channel surface raceway profiles — confirm compatibility with your existing raceway system (Wiremold AL or Middle Atlantic AL series) before ordering to avoid fit issues.
• Precise dimensions (2-7/8 x 1-13/16 inches): Engineered to match raceway cross-section — ensures flush termination without gaps that would require additional sealing or leave cable exposed at the end.
• Blank (unpunched): No pre-drilled holes for cable exit — allows you to drill or cut openings on-site to suit your specific wiring layout, minimizing waste on custom runs.
• Low profile: Adds minimal bulk to raceway termination — ideal for tight cable closets or installations where every inch of clearance counts.

Integration & Compatibility

The AL3310B is designed for Wiremold AL and Middle Atlantic AL surface raceway systems commonly deployed in commercial surveillance networks, access control wiring, and data infrastructure. Verify that your existing raceway channel width and profile match the 2-7/8 x 1-13/16 inch footprint before installation. This fitting does not include fasteners; mounting typically uses existing raceway track bolts or adhesive backing compatible with the parent system. Consult the raceway manufacturer's assembly guide to confirm attachment method for your specific installation.

Frequently Asked Questions

Q: What raceway systems does the AL3310B fit?

A: The AL3310B is designed for Wiremold AL and Middle Atlantic AL series single-channel surface raceways. Verify your raceway's cross-section dimensions (2-7/8 x 1-13/16 inches) match before purchase.

Q: Is the AL3310B weather-rated for outdoor use?

A: The satin anodized aluminum finish is corrosion-resistant and suitable for covered outdoor areas (eaves, sheltered sidewalls). For full outdoor exposure with rain and direct UV, consult Middle Atlantic for outdoor-rated end fittings or protective shrouding.

Q: Can I drill the blank end fitting to add cable exits?

A: Yes. The blank design allows on-site drilling or cutting to suit your cable routing. Use standard metal drill bits and deburr edges after drilling to prevent cable abrasion.

Q: Does the AL3310B come with mounting hardware?

A: No fasteners are included. The fitting typically mounts using the same bolts or adhesive backing as your parent raceway system — refer to the raceway manufacturer's installation manual for specifics.

Q: What is the satin anodized finish rated for in terms of durability?

A: Satin anodize provides a Type II anodic coating, standard for indoor and covered outdoor cable management — offers excellent corrosion resistance in most commercial environments. High-salt or industrial chemical exposure may require periodic cleaning.

The AL3310B blank end fitting is a straightforward but essential component when you're terminating surface raceway runs in surveillance cable plants. The satin anodized aluminum construction paired with the 2-7/8 x 1-13/16 inch footprint gives you a professional-looking endpoint that matches the parent raceway and won't rust out over years of service in humid equipment rooms or outdoor cable enclosures.

Technical Highlights:

• Satin anodized aluminum: Type II anodic coating resists corrosion in typical commercial environments (humidity, occasional splashes, covered outdoor placement) — much more durable than bare aluminum or painted steel alternatives that chip and oxidize.
• Blank (unpunched) design: Allows custom drilling on-site for cable exits or conduit stub-outs — you're not locked into factory-drilled holes that don't match your wiring plan. Saves money on custom-molded versions.
• Precise fit to AL series raceway: The 2-7/8 x 1-13/16 inch dimensions are engineered for flush mating with Wiremold AL and Middle Atlantic AL channel profiles — eliminates gaps that would otherwise require filler strips or additional sealing.

Deployment Considerations:

• Confirm your existing raceway cross-section matches before order — AL3310B will not fit standard 4x4-inch wireways or significantly oversized channels. Measure your raceway first.
• The blank end fitting provides no built-in cable management (no knockouts, no strain relief) — if you need to route cables through the fitting itself, plan to drill and debur on-site or add a separate transition fitting downstream.

Position the AL3310B when you're building a surveillance network over a drop ceiling or running access control wiring through a cable trough — it's the right choice for a clean, non-corroding termination that will still look professional five years from now.
