Troubleshooting
Tie feels loose within the mortar joint
Ensure the embedment depth is at least 62.5mm and that the mortar mix is of appropriate consistency to provide a firm grip.
Difficulty seating the 38mm upstand
Verify that the masonry surface is level and that you have cleared any excess mortar obstructing the placement of the upstand.
Pros and Cons

- High shear load capacity of 1180N for heavy-duty stability
- Essential for preventing sideways movement in non-structural masonry elements
- Compact design ideal for tight timber-to-masonry installations
- Easy to integrate into standard mortar joints of 10mm or larger
Cons
- Single unit packaging may require planning for multi-point installation projects

Setup, Compatibility & Care
To ensure the longevity and effectiveness of the cramp, follow these guidelines:
- Preparation: Ensure the masonry joints are clean and free of loose debris before placing the cramp.
- Placement: Insert the tie so that the 62.5mm portion is fully embedded within the mortar.
- Compatibility: Only use this product in applications where the mortar joint is at least 10mm deep and wide.
- Alignment: Check that the 38mm upstand is perfectly vertical against your timber frame before fixing the frame to the tie.
- Maintenance: Regularly inspect visible parts of the frame and surrounding masonry to ensure no mortar has cracked or shifted, which could expose the tie to moisture and reduce its structural effectiveness.
