Regarded as the standard fixing solution for many items found in the pool environment, both standard and springloaded holdfast fixings are manufactured entirely from 316 stainless steel. Holdfast fixings provide a versatile fixing system which can be used for starting blocks, turning boards and lane lines. As a standard they are M10 size thread. The holdfasts are grouted into pool wall/floor and the eyebolt secures the product/lane line hook. The springloaded cover variant covers the hole instead of a screw fixing.
