carpet grips: doubled up?

[Stephen]

Hello,

I read an old post here that suggested if your carpet was over a certain length, you should run two rows of carpet grips but I don't think there was a resounding consensus. Our lounge carpet will be about 5m by 3m, my interpretation of this earlier post is that the 5m stretch should have doubled up grips but the 3 m wide bit only needs a single row. Would you agree? When I removed the old carpet there was a single row of grips on three sides but a double row on the fourth wall. Was a double row necessary or did they put it in because the first set was loose!?

Thanks in advance.

Never seen a double row. Suppose it might be an idea where they're glued to a concrete floor etc. But don't think there's any need if they can be fixed normally.

Mine have clips that go under the skirting to stop the carpet twisting them up.

I've recently had a new hallway carpet fitted, going over a few of my network cables running parallel but separated from the skirting by the original gripper1 below.

-------- skirting

++++++++ gripper1 ======== cables ======== cables ++++++++ gripper2 underlay ....

Carpet guy came in and put an additional gripper2 before proceding putting new underlay for some reason(?). If it had been lazy me I probably would have laid the carpet with the original gripper1.
