Removable-Base Post Holders

Removable-Base Post Holders

OptoSigma’s removable base post holders have a through hole on the side for tightening and loosening the post with a hex wrench.  We also offer high stability ball plunger used for coarse/fine rotation and height adjustments of posts.  This offers three points of contact with the post holder as opposed to the conventional two contact points preventing posts from slipping as well and smooth adjustment with one hand when the clamp is loosened.  The adjustment screw on the bottom of the post holder can be rotated in 90-degree increments and can be mounted with different adapters.  Please fill out our custom request form for custom OEM applications.
