The one basic guide frame is standard for ALL "Z" and "U" section piles and ALL straight web piles.

The different sections are accommodated simply by inserting appropriate rollers onto the lower spindles which form part of the lower clamp.
These rollers fit the pile profile to give positive
and accurate location. Different stop plates are attached to the top grip to suit different pile sections.

With one pile section there may be several variations. On "Z" sections the interlocks are usually different at each end. The leading end can also be left hand or right hand.

The pile threader can accommodate these variations by swapping the rollers round on the lower grip spindles to accommodate changes in handling and by replacing some elements of the rollers to accommodate the different inerlock.

On "U" sections the interlocks are identical and the only variations are on handling.
