L H Dottie TBC384 Toggle Bolt 3/8 X 4 Inch

Product Description

The L H Dottie TBC384 is a toggle bolt fastener designed for anchoring fixtures and equipment to hollow walls and ceilings. With a 3/8-inch diameter and 4-inch bolt length, this fastener uses a spring-loaded wing anchor that collapses for insertion through a drilled hole and expands behind the cavity wall to distribute load. It is sold individually and suited for use by electricians, HVAC mechanics, plumbers, and general contractors who need a reliable hollow-wall anchor in light commercial and residential applications.

This toggle bolt is used in mounting applications where the substrate lacks solid backing, such as drywall, plaster, or hollow block. Typical uses include securing conduit hangers, junction box brackets, light fixture mounting plates, and similar trade hardware to interior walls and ceilings. The 3/8-inch diameter makes it appropriate for moderate-load mounting tasks common in mechanical and electrical rough-in work.

Key Features

• 3/8-inch bolt diameter for moderate-load hollow-wall anchoring
• 4-inch bolt length provides reach through thicker wall assemblies
• Spring-loaded wing toggle expands behind the wall cavity for secure grip
• Sold individually, allowing quantity purchasing matched to job requirements
• Suitable for drywall, plaster, and hollow masonry substrates

Compatibility

Designed as a standard toggle bolt anchor for use in hollow wall and ceiling installations common in residential and light commercial construction.

Installation Notes

Installation is performed by drilling a hole sized to allow the folded toggle wings to pass through, threading the fixture onto the bolt, inserting the assembly, and pulling back to seat the wings against the interior wall surface before tightening. A drill and appropriate bit are required. Always confirm the wall or ceiling material and the load rating of the anchor before installation, and follow applicable building codes for the jurisdiction. Do not overtighten, as excessive torque can pull the wings through the substrate.
