Post Holder 50 mm Long M6 Thread

Ealing Half-inch Post Holders are double-bored to provide a groove opposite the knurled locking screw. This gives two-lines of contact for a precision, centered fit on any Half-inch Post. Posts are locked in place by a knurled, spring loaded brass thumb screw located at the top of the Post Holder and drawn in cross section at left.

Ealing’s range of Half-inch Posts can be supported in a variety of fixed and adjustable mounts. These include our range of fixed length post holders shown here. The post holders in turn may be mounted onto optical tables, breadboards, or metric and inch positioners directly or through one of our mounting bases. The posts then provide fixed or adjustable locations for Ealing’s wide range of component mounts including lens holders, Precise™ Mirror Mounts, Prism/Beamsplitter Mounts and Filter Holders.
