Product Description
Simpson ABL Anchor Bolt Locator with 3/4 in. Nut delivers accurate, secure placement of anchor bolts on concrete-deck forms before concrete is poured. The structural heavy-hex nut is attached to a pre-formed steel chair, eliminating the need for an additional nut on the bottom of the anchor bolt and reducing setup steps during formwork. The chair design is optimized for concrete flow, helping contractors achieve consistent bolt positioning across foundation and slab applications.
Key Features
- Optimized chair geometry for concrete flow - allows concrete to move freely around the locator, reducing the risk of voids or honeycombing near the anchor bolt
- Installs with (2) nails or (2) screws - fast, tool-friendly attachment to the deck form means less time spent on individual bolt setup
- Provides 1 in. standoff (clear cover) for anchor bolts - automatically positions the bolt at the correct embedment depth, removing guesswork and helping meet cover requirements
- Integrated heavy-hex nut eliminates a separate bottom nut - simplifies the assembly process and keeps components together before and during the pour
- Chair finished in Galvanized (G90) - corrosion-resistant coating protects the chair through wet concrete exposure and site conditions
- Compatible with anchor rod diameters from 1/2 in. to 1-1/4 in. across the ABL line - this model is sized specifically for 3/4 in. anchor bolts, making it easy to order the right fit for your bolt specification
Why This Product
- Eliminates a common installation step - because the heavy-hex nut is pre-attached to the steel chair, crews skip the extra nut on the bottom of the rod, cutting assembly time and reducing the chance of missing hardware during a pour
- Built-in standoff means built-in accuracy - the 1 in. clear cover height is set by the chair itself, so anchor bolt depth stays consistent across the form without manual measuring at each location
- Made in the United States by Simpson - a manufacturer with a long record in structural connectors and anchoring products, giving buyers confidence in material quality and dimensional consistency
- Electro-galvanized versions available for HDG anchor bolts - the ABL product family is designed to pair correctly with different bolt finishes, so the locator can be matched to the specific bolt specification on the job
