Scaffold wall ties are typically placed on a grid every 4 metres or so vertically and horizontally, but the exact spacing depends on the scaffold height, sheeting and wind exposure. More ties are needed if the scaffold is clad with netting or sheeting that catches wind. A scaffold designer or the system's load tables set the final pattern.

Scaffold anchor tubes are made from galvanised steel so they resist rust while fixed into a wall outdoors for the life of the scaffold. The hooked or threaded end grips the anchor point while the tube body connects to the scaffold. Galvanising protects the tie through wet weather and long site periods.

A scaffold anchor tube is fixed to a wall by hooking or bolting it into a ring anchor or expansion anchor set into the masonry, then clamping the other end to the scaffold with a coupler. The hook end locates in the fixing while the tube spans back to the standard or ledger. The anchor must go into sound brick, block or concrete, not just render.

Yes, scaffold anchor tubes are made from 48.3 mm tube so they connect to the scaffold with standard right-angle or swivel couplers. The wall end carries a hook or eye that engages the anchor bolt in the structure. This lets each tie resist both push and pull forces between the scaffold and the wall.
