Product Information
Full details
The AB Tools Safety End Frame Clamp Cramp is an essential component for contractors and DIY enthusiasts tasked with securing masonry to existing structures, such as timber window and door frames. These stainless steel ties provide critical lateral stability, preventing unwanted movement between building elements to ensure long-term structural integrity. While they offer excellent durability and resistance to environmental degradation, they are specifically engineered for a 10mm mortar joint, which may require careful planning during the construction phase to ensure a proper fit.

FAQs
What is the material composition of these cramps?
These cramps are manufactured from grade 304 stainless steel, which is highly resistant to rust and corrosion.
Can I use these for structural load-bearing walls?
No, these are designed for restraining masonry to frames and non-structural elements, not as primary structural wall ties.
How many cramps come in a pack?
Each pack contains 20 individual frame clamps.
What is the required mortar joint size?
These are designed for a 10mm minimum mortar joint.
What is the shear load rating?
The shear load capacity is 1180N.
What is the minimum embedment depth?
The recommended minimum embedment depth is 62.5mm.
Troubleshooting
The clamp does not fit in the mortar joint.
Verify the mortar joint is at least 10mm wide. If the joint is narrower, the mortar must be adjusted or the brickwork level corrected.
Movement noticed in the frame after installation.
Ensure that the required number of cramps were used along the length of the frame and that the embedment depth of 62.5mm was achieved.
Pros and Cons
Pros
- Superior corrosion resistance due to 304 stainless steel construction
- High shear load capacity of 1180N ensures structural safety
- Easy to integrate into standard masonry construction
- Provides reliable lateral restraint for door and window frames
Cons
- Requires a specific 10mm mortar joint for correct installation
- Limited to masonry-to-frame applications
- Not suitable for load-bearing structural wall ties
Setup, Compatibility & Care
To ensure maximum effectiveness, the following guidelines should be observed:
- Mortar Joint Compliance: Ensure that all affected mortar joints are at least 10mm thick to accommodate the thickness of the clamp.
- Installation Depth: Verify that the tie is embedded at least 62.5mm deep into the masonry mortar to maintain the rated shear load capacity.
- Compatibility: These are intended for use with standard timber window and door frames. Always use corrosion-resistant screws when securing the upstand to the timber frame to match the longevity of the stainless steel clamp.
- Care: Keep the ties free from debris and contaminants before embedding in mortar to ensure a clean bond. Once installed and covered in mortar, the grade 304 stainless steel requires no ongoing maintenance.
