Acorn M143J Spring Wing Toggle Bolt

Product Description

The ACORN M143J is a spring wing toggle bolt designed for fastening into hollow walls and ceilings where standard screws lack adequate holding strength. The toggle mechanism uses spring-loaded wings that expand behind the wall surface once inserted through a drilled hole, distributing load across a wider bearing area. This type of anchor fastener is commonly installed by electricians, plumbers, and general contractors when securing fixtures, conduit hangers, pipe straps, or equipment brackets to drywall, plaster, or similar hollow substrates.

The M143J is suited for light to medium-duty anchoring applications in both residential and light commercial settings. Typical installations include securing electrical boxes, junction box supports, HVAC duct hangers, pipe supports, and other trade hardware to hollow wall or ceiling assemblies where backing material is not accessible from behind.

Key Features

• Spring-loaded wing design expands behind the wall surface for secure anchoring in hollow substrates
• Suitable for drywall, plaster, and similar hollow wall or ceiling materials
• Reusable bolt design allows removal and reinstallation without losing the toggle body
• Applicable across multiple trades including electrical, plumbing, and HVAC rough-in work

Compatibility

Designed as a standard spring wing toggle bolt for general hollow-wall anchoring applications across residential and light commercial construction and mechanical trades.

Installation Notes

Installation requires drilling a clearance hole sized to allow the folded toggle wings to pass through the substrate. Thread the bolt through the fixture being mounted before inserting the toggle through the wall. Once the wings spring open behind the substrate, pull the bolt outward while tightening to seat the wings firmly against the back surface. Follow applicable building codes and load rating guidelines for the specific substrate and application.
