Threlaco Double Shear Seat Belt Tabs 4-Pack — 1/2" Hole Weld-On Iron Tabs, Flush Base

Threlaco 4-pack double shear seat belt tabs are welded mounting brackets with 1/2" holes designed to attach safety harnesses and limit straps securely to roll cages, frames, and chassis.

These weld-on limit strap tabs are built for fabricators, off-road builders, and UTV enthusiasts who need a reliable, compact mounting point for harnesses and suspension limit straps. Machined from iron with a flat base to sit flush against tubing or plate, each tab accepts standard harness hardware and is sized to work with a broad range of straps and bolts. Sold in a set of four, they simplify creating multiple, consistent attachment points during a single build or repair session.

How strong are these tabs once welded in place?

When welded correctly to a clean, compatible surface, the iron construction and flat-base design yield a robust attachment point suitable for repeated use. Strength depends on weld quality and parent material; full-penetration welds on appropriate tubing or plate provide the best load handling.

• Made from iron to accept standard MIG/TIG stick welds
• Flat base aids secure, even weld beads for consistent strength
• Designed for double shear loading with harness hardware
• Recommended to weld to structural tube or steel plate only

What sizes and hardware fit these limit strap tabs?

Each tab is sized to accommodate common harness and strap hardware. The hole thickness and inner diameter match many off-road and racing components, so you can usually pair them with widely available bolts and clevis-style fittings.

• 1/2" hole diameter for main attachment bolt compatibility
• 1/8" to 1/2" material thickness range per side for versatile fit
• 5/16" inner gap dimension for strap linkage clearance
• 1 1/4" center-to-bottom distance enables easy alignment to tubing

Are these tabs easy to install for DIY builders?

Yes — they are intentionally straightforward for both experienced fabricators and weekend DIYers. The simple, flat-footed shape makes placement and tack-welding quick, and their consistent dimensions help speed repeat installations.

• Flat mounting pad speeds clamping and tack procedures
• User-friendly shape simplifies alignment on round or flat surfaces
• Can be welded by MIG, TIG or stick depending on shop preference
• Sold in a four-piece set for multiple mounting points in one build

How should I manage corrosion or rust during shipping and storage?

Parts ship untreated and may develop surface rust during extended transit; light surface corrosion doesn't affect weldability or function but should be addressed before final assembly for appearance and longevity. Remove rust with a wire brush or chemical rust remover, then prime or paint after welding if desired.

• Rust-free at factory but possible during long shipping
• Clean with wire brush or rust remover before welding
• Prime or coat after installing to improve long-term corrosion resistance
• Inspect welds and surfaces periodically in harsh environments

Who is this for: Threlaco double shear seat belt tabs suit automotive fabricators, off-road and UTV builders, race teams, and hobbyists who need compact, consistent weld-on anchor points for safety harnesses or limit straps. If you weld your own roll cage, reinforce chassis attachments, or create custom mounting plates, these tabs offer a simple, repeatable solution for securely attaching straps and hardware.
