SpanSet Xtirpa Manhole Collars are ideal for round entry holes as found on tanks, tankers and ground manholes. They cleverly utilise compression onto the manhole to enable an easy portable attachment which can take the standard 610mm davit arm and mast. Designed for applications involving frequent set ups over similarly-sized access openings. This lightweight and easy to assemble/disassemble system provides a portable adapter base and certified anchor point. Ideal option for areas where a permanent anchor is not viable. Can also be used with the the low headroom davit and short reach davit. Available in anodised finish and offset base for angled tank lids. Please contact us for size availability.
