Appleton TWCL-50MN 1/2 Inch Single-hole Emt Clamp

Product Description

The APPLETON TWCL-50MN is a single-hole EMT conduit clamp designed to secure 1/2 inch electrical metallic tubing to structural surfaces such as walls, ceilings, and framing members. This clamp provides a firm, code-compliant mechanical support point for EMT runs in residential, commercial, and light industrial wiring installations. Electricians use these clamps during rough-in and finish wiring stages to meet NEC spacing requirements for conduit support. The design allows for quick, one-fastener installation, reducing labor time when securing long conduit runs with multiple support points.

This clamp is suited for use in standard EMT installations where 1/2 inch conduit is routed along framing, concrete, masonry, or steel surfaces. Typical applications include branch circuit wiring, feeder runs, and equipment connections in both new construction and retrofit projects. The single-hole mounting pattern keeps the installation footprint small, making it practical in tight spaces and congested panel areas.

Key Features

• Fits 1/2 inch EMT conduit for a secure, stable support point
• Single-hole mounting design speeds up installation along long conduit runs
• Suitable for indoor structural mounting to wood, concrete, masonry, and steel
• Supports NEC-compliant conduit spacing when used at proper intervals
• Sold in quantity packaging, reducing per-unit cost on larger jobs

Compatibility

Designed as an OEM-style support fitting for use with standard 1/2 inch EMT conduit in commercial and residential electrical installations.

Installation Notes

Installation is performed by a licensed electrician. De-energize any circuits in the work area before securing conduit near existing wiring. Use a fastener appropriate to the mounting surface — concrete anchors for masonry, wood screws for framing, or self-tapping fasteners for steel. Follow NEC Article 358 guidelines for EMT support spacing to ensure code-compliant conduit runs.
