2PCS Prism Adapter 20mm 5/8 x11 Thread Male to Female Thread for Prism Tribrach GPS Total Station Adaptor Overview Compact adapters that convert a 5/8 x 11 male thread to a 20mm female mount, enabling secure connection between prisms, tribrachs, GPS receivers and total stations. Sold as a set of two for spare or multiinstrument use. Key benefits Restores compatibility quickly: Convert mismatched threads on prisms and tribrachs without replacing equipment. Reduces downtime: Fast installation on site keeps surveying and layout work moving. Stable connections: Designed to provide a secure mating between instrument and accessory for reliable measurements. Compact and portable: Small footprint fits easily in a field case or toolbox for convenient transport. Cost effective: Use existing prisms and tribrachs across different instruments by adding the adapter. Specifications and function Quantity: 2 pieces per package Conversion: 5/8 x 11 male thread to 20mm female mount Primary function: Thread adapter for attaching prisms, tribrachs, GPS units and total station accessories when thread types differ Fit: Intended for standard 5/8 x 11 threaded instrument mounts and 20mm prism mounts How it solves common problems Thread mismatch: Eliminates the need to prisms or tribrachs by adapting existing threads. Multiinstrument setups: Allows a single prism or tribrach to be used with multiple instruments that have different thread sizes. Field repairs: Serves as a quick replacement part when an adapter is lost or damaged during fieldwork. Easy to use Screw the adapter onto the 5/8 x 11 male thread, then attach the prism or accessory into the 20mm female mount. No special tools required for standard tightening. Typical applications Field surveying: Attach a reflector prism to a tribrach or instrument with differing thread interfaces during topographic surveys. Construction staking and layout: Rapidly adapt prisms or GPS receivers for use on different tripods or tribrachs at multiple site locations. Geodetic and cadastral work: Use as a spare adapter to keep multiple total stations and receivers interchangeable during measurement campaigns.
