Chain Pipe - Circular Medium
An all stainless steel investment cast (one piece base)
Chain pipe with hinging lid.
Maximum outside diameter 95mm of outer flange. Hole size required in deck 70mm. Actual hole size that your chain + rope passes through is 65mm diameter, and a well placed slot allows your chain to remain in that slot - designed for up to 8mm short link chain (+ a larger rope of course)
Being S/S, a very small amount of grinding would allow 10mm chain in the slot with the lid shut, also useful for use as other deck fitting hatch way access.
