Not like roger Oates,a customer gave a friend the sample to see if he knew what it was,she cannot remember what it was.
I once got asked to fit that roger oats stuff, she had a box of pinless gripper and said it must be fit bottom to top...
She's right although should be short pin or microplast gripper batten on bottom step and wrap it under it's self for moving in future
The fitting instructions stating pin gripper are out of date. It is recommended to use microplast gripper now. But as with anything you can fit it any way you wish but the correct way is microplast.
