Product Overview
Stainless steel frame cramp with a 100mm projection. Designed for restraining masonry panels or cavity walls to structural frames, these cramps provide secure mechanical connection between brickwork and structural supports.
Manufactured from high-grade austenitic stainless steel for maximum corrosion resistance, they deliver long-term durability in exposed or damp environments. Each cramp is precision-formed with a pre-punched fixing hole and return leg for consistent anchorage and ease of installation.
The 100mm projection offers a moderate offset, ideal for typical cavity widths and standard wall constructions.
Features & Benefits
- Material specification: Manufactured from austenitic stainless steel for long-term corrosion resistance and mechanical reliability.
- Formed profile: Angled return leg ensures consistent embedment in mortar joints, providing secure load transfer.
- Pre-punched fixing hole: Allows direct screw or bolt fixing to concrete, steel, or timber frames for fast and accurate installation.
- Load performance: Designed to accommodate both vertical and lateral restraint forces within masonry support applications.
- Durability: Resistant to moisture and chemical exposure, maintaining structural integrity over extended service life.
- Projection length: 100mm projection suitable for standard cavity wall widths and general-purpose masonry restraint.
Applications
- Cavity wall restraint: Used to tie external masonry to internal structural frames.
- Brickwork support: Provides secure anchorage where brick panels are supported against movement or wind load.
- Timber or steel frame connection: Fixes masonry leaves to non-masonry backing structures.
- Standard cavity width use: Optimised for 100mm cavity spacing in typical external wall assemblies.
Installation Guidance
- Fixing preparation: Ensure substrate is clean, flat, and capable of supporting the restraint load.
- Positioning: Align the cramp so the return leg sits horizontally within the mortar bed joint.
- Fixing method: Secure to the frame using a suitable stainless steel screw or anchor through the pre-punched hole.
- Mortar embedment: Fully bed the return leg in fresh mortar to ensure full bond strength.
- Inspection: Check alignment and embedment depth before the mortar cures.
Compliance & Performance
- Material grade: Austenitic stainless steel to BS EN 10088 for structural durability and corrosion protection.
- Manufacturing standard: Produced in accordance with BS EN 845-1 for wall ties, straps, and cramps.
- Performance testing: Meets restraint capacity requirements for cavity wall construction.
- Corrosion resistance: Suitable for external and coastal environments.
- Important note: Always use with compatible stainless steel fixings to prevent bi-metallic corrosion.
