Can anyone please help me regarding the thickness of underlay relative to the thickness of the gripper rod. I have an 11mm thick underlay which I am putting on top of an aluminium foil faced PE foam which is 5 mm thick - total thickness 16 mm. Obviously this is much thicker than a gripper rod which is about 6 mm.
My question is - how much packing do I need to put under the gripper rod? i.e. with what does the top of the underlay have to line up with: exactly with the top of the wood of the gripper (excluding the spikes), or just above or just below the wood?
Thanks.
