Ratchets are required to tension your Studrail. Studrail has
high tensile wire inside and this needs to be pulled tight.
Please see our erection instructions as your tensioning posts need to be secure.
Tension is achieved by drilling holes through the post and then
passing the wires through the post and central drum of the ratchet.
The Ratchet can then be wound using a spanner.
We recommend you put Ratchets on both ends for runs over 50 metres.
Two Ratchets are required per end of rail.
