Product Description

Clamping diameter: Ø25 mm;
Base-type Ø25 mm flexible post holder allows post penetration for greater height adjustment range;
With flexible locking mechanism, various lengths available;

The Ø25 mm flexible post holder from LBTEK is designed for clamping Ø25 mm posts, available in two types: the Ø25 mm standard flexible post holder and the Ø25 mm base-type flexible post holder. The difference is that the Ø25 mm standard flexible post holder (FPH-xxA series) features an M6 tapped through-hole at the bottom, preventing the post from penetrating the holder and maintaining 6.1 mm minimum spacing from the platform surface. On the other hand, the Ø25 mm base-type flexible post holder (FPH-xxB series) features a Ø47×6.1 mm base at the bottom, which can be used in conjunction with the LBTEK clamping fork PHC1.5 for flexible installation on optical platforms. Its center has a fully through-hole to satisfy the minimum beam height requirement. Both types of post holders have a circular groove and a square groove. The circular groove allows the metal to bend under force, thereby securing the post. After locking, the square groove forms two fixed contact lines with the post to ensure maximum clamping force. The flexible locking function can be achieved by using an M4 socket head cap screw.

Ø25 mm Standard Flexible Post Holder

Standard flexible locking post holder for Ø25 mm posts
Bottom M6 tapped through-hole;
Post holder heights: 38 mm, 50 mm, 75 mm, 100 mm;

The Ø25 mm standard flexible post holder from LBTEK can be locked by tightening the M4 socket head cap screw on the clamping arm with a 3 mm hex key. The circular groove on the center hole permits the metal to bend to secure the post without fracture. After locking, the square groove forms two fixed contact lines with the post to ensure maximum clamping force. Featuring an M6 mounting tapped hole at the bottom, this post holder can be flexibly mounted on optical breadboards when paired with LBTEK post bases (PRB-1) or mounts (PB-x series), or secured directly via M6 screws.

The Ø25 mm flexible post holder is often used in conjunction with mounts.

Ø25 mm Base-type Flexible Post Holder

Base-type flexible locking post holder for Ø25 mm posts;
Post holder heights: 38 mm, 50 mm, 75 mm, 100 mm;
Compatible with clamping fork PHC1.5 for post holder;

The Ø25 mm base-type flexible post holder from LBTEK can achieve flexible locking by using a 3 mm hex key to tighten the M4 socket head cap screw. The circular groove design allows the metal to bend, thereby securing the post. After locking, the square groove forms two fixed contact lines with the post to ensure maximum clamping force. The center through-hole of the base-type flexible post holder runs fully through to the bottom, satisfying the minimum beam height specification. The bottom features a Ø47×6.1 mm mount, which can be used together with the clamping fork PHC1.5 for post holders for flexible fixation on an optical breadboard.

Ø25 mm base-type flexible post holder is often used in conjunction with clamping fork for post holder.
