SPIRA-LOK: The Original Helical Wall Tie System

The Spira-Lok is a one-piece, flexible stainless steel wall tie designed for pinning masonry to new or existing walls. It is also ideal for temporary support during lintel or shelf angle replacement. The innovative dry-set technique simplifies installation with minimal disruption.

Features 

• Installation requirement: Requires compatible Spira-Lok® setting tool for proper installation.
• Small pilot hole: Requires only a small-diameter hole, reducing substrate damage.
• No adhesives or expansion devices: Toxic-free and safe for various applications.
• Immediate testing: Tie functionality can be verified on-site immediately after installation.
• Versatility: Works effectively across a wide range of building materials.
• Cyclic load resistance: Performs well under dynamic conditions.
• Differential movement: Accommodates movement between dissimilar materials.
• Substrate-safe: Minimizes stress or fractures, even in fragile substrates.

Installation Requirements 

Spira-Lok® ties require the use of a compatible Hohmann & Barnard Spira-Lok® setting tool for proper installation.

Note
An on-site survey is recommended before tendering to assess:

• Material strength
• Appropriate tie diameter and length
• Pilot hole size
• Optimal drilling techniques
