Types of scaffold ties It is essential that all scaffolds are properly tied into the building or structure at intervals to ensure the safety and stability of the scaffold.

Through Tie
A tie fixed through an opening in a wall or a window.
Reveal Tie
A reveal tube with wedges or screwed fittings and pads, fixed between opposing faces of an opening in a wall together with the tie tube. Relies solely on friction, therefore safe working capacity is reduced. Ideally, they should not be more than 50% of the total number of ties.
Box Tie
The assembly of tubes and couplers, usually around columns or other elements of the building. The above types of the tie are all of the moveable variety, this means they can be removed, one at a time systematically then replaced after the task necessitating the removal is complete.

Cast-in and Drilled Anchorages
Provided by casting in, or fixing a threaded anchor sleeve into the structure itself. The attachment of the scaffold to the anchor sleeve is either by a ring bolt or tied and secured by wire lashing. These types should be used in accordance with the manufacturer’s recommendations. The capacity of the anchorage into the structure must be established by test, 50% need to be pull tested.
