Appleby 1-Gang 35mm Dry Lining Box

About this product

The Appleby SB519 1-Gang 35mm Dry Lining Box is the industry-standard choice for mounting electrical accessories into hollow, plasterboard, or dry-lined walls. Designed for quick, secure fitting, it features dual adjustable yellow lug clips that firmly sandwich board thicknesses from 6.35mm to 15mm. Large top and bottom flanges combined with robust spring clips hold the box securely against drywall to prevent push-through during plug insertion. Includes multiple side, top, and base knockout points for easy 20mm conduit or cable entry. Manufactured from durable, high-impact thermoplastic materials rated to BS EN 60670-1. Ideal for deeper switches, USB power sockets, dimmer switches, and standard wiring accessories. Single brass pillar clip provides fine adjustment when mounting sockets and frontplates flush against the wall surface.
