Cranked Eye Bolt - Uses

Uses

The requirement for an offset tie down will occur when vermin proofing must be placed between the column or post, and a wooden bearer, for example to stop termites travelling up through a concrete or wooden post or column directly into the bearer and the rest of the building. The "ant capping", typically a 0.5mm to 0.8mm thick galvanised steel sheet, must be placed between the post and the bearer overlapping the perimeter of the post by approximately 20mm to 40mm or more. The cranked eye bolt is fastened to the post using a bolt though the eye, the crank in the shaft allowing the shaft to be positioned so that it does not impede the overlap of the "ant capping" up through the bearer.

Should termite attack occur, the post of column can be replaced with no structural effect to the building.

Cranked eye bolts can also be used to tie the top plate of a house frame directly to house supports, using rod couplers and steel extension rods.
