140mm Enclosure Mount Adapter – For 2.5" Carport Clamping System

140mm Enclosure Mount Adapter – For 2.5" Carport Clamping System

Securely mount weatherproof electrical boxes, solar disconnects, networking enclosures, or automation equipment directly to carport columns without drilling into structural steel. Engineered to interface with our 2.5" Square Post Clamp Base, this adapter plate bridges standard 140mm on-center mounting hole patterns directly to your post using our slide-and-snap system.

Key Features

• Precision 140mm Spacing: Engineered specifically with 140mm (approx. 5.51") on-center hole spacing, matching a wide range of standard outdoor electrical boxes, junction enclosures, and control cabinets.

• Clean, No-Drill Equipment Mounting: Eliminate self-tapping screws and drill holes that compromise the galvanized coating and structural integrity of your posts.

• Modular Slide-and-Snap Fit: Fastens directly to the back of your enclosure and drops straight into the base clamp collar's receiver slot for a rigid, secure installation.

• Dual-Clamp Ready for Heavy Enclosures: Use a single adapter for small utility boxes, or pair two adapters with two base clamps (top and bottom) for taller, heavier industrial control boxes.

• All-Weather Outdoor Durability: Engineered to withstand prolonged UV exposure, temperature swings, and outdoor moisture in open-air carports, barns, and shops.
