Step 1

Initially cut out a small section of the existing seal and push fit a similar sized piece of the new seal to ensure the fit is acceptable.

Step 2

The new seal is lubricated but if additional lubricant is required we recommend using a small amount of washing up liquid.

Step 3

Please note that the arrowhead is offset from the centre so you can fit it either way to suit to gain better coverage.

We hope you enjoy the benefits of renewing your worn seals to prolong the life and increase the performance of your doors and windows.
