Features
- Clamp Cylindrical Objects Ranging from Ø0.47" (Ø12.0 mm) to Ø2.09" (Ø53.0 mm) (See Table to the Right)
- V-Block Mounting Length of 0.60" (15.2 mm)
- Stainless Steel Band Provides Distributed Clamping Force for Circumferential Grip
- Five Bands Available Separately for Securing Components of Varying Diameters
- VCP(/M) Band Clamp Includes VCPL55 Band for Components from Ø29.0 mm (Ø1.14") to Ø37.0 mm (Ø1.46")
- Ø1/2" (Ø12.7 mm) Post for Use in Ø1/2" Optical Post Assemblies
The VCP(/M) V-Post Band Clamp uses a stainless steel band to contact a mounted component over an extended area. A bronze knob at the bottom of the clamp can be used to tighten or loosen the clamp for mounting purposes. Once a component is securely mounted, the band can be locked in place using a 5/64" (2.0 mm) hex key on the locking screw located on the side of the post. These clamps feature a single band and a 0.60" (15.2 mm) long V-block, making them ideal for components with only a short section that can be clamped. The body of the clamp is a Ø1/2" (Ø12.7 mm) stainless steel post with a 2.10" (53.2 mm) long mounting surface, which can be integrated with Ø1/2" optical post assemblies, Ø1/2" (Ø12.7 mm) post holders, and accessories. A 1/4"-20 (M6 x 1.0) mounting hole can be found on the bottom of the bronze knob for additional mounting options. These clamps are best used for holding cylindrical objects such as Fiber Collimation Packages, Laser Diode Modules, and HeNe Lasers. For objects that have unusual shapes or are easily marred post-mountable V-clamps, including VBC1(/M) and VBC2(/M) band clamps, are recommended.
Each VCP(/M) V-post band clamp includes a VCPL55 band, which is 139.7 mm (5.50") long and allows for the mounting of components with diameters from Ø29.0 mm (Ø1.14") to Ø37.0 mm (Ø1.46"). Four alternative stainless steel bands, as well as a replacement for the VCPL55 band, are available separately below with the minimum and maximum diameter for each band given in the table above. For securing objects with diameters outside of the Ø12.0 mm (Ø0.47") to Ø53.0 mm (Ø2.09") range, other V-mounts are available.
The stainless steel band of the VCP(/M) band clamp can easily be exchanged with one of the other available bands to clamp both larger or smaller components. To do so, make sure that the clamp is not locked by loosening the locking screw on the side of the post with a 5/64" (2.0 mm) hex key. Loosen the band by turning the knurled bronze knob at the base of the clamp counterclockwise, until the captive band interchange screw is visible through the release hole near the top of the clamp. Using a 5/64" (2.0 mm) hex key, unscrew the band interchange screw and remove the band. Replace the band with one of the desired size and bend it such that the holes on either end of the band are aligned with each other. Insert the ends of the band into the top of the clamp, aligning the holes with the band interchange screw and then secure the band in place by tightening the screw. The band should feel loose when properly engaged by the interchange screw.

This clamp uses a stainless steel band that contacts the mounted component over an extended area around its circumference. A bronze knob at the bottom of the clamp allows for the clamp to be tightened or loosened, while a side-located locking screw (5/64" [2.0 mm] hex) secures the band in place. The clamp features a single band and 0.60" (15.2 mm) long V-block and is ideal for components with only a short section that can be clamped. The Ø1/2" (Ø12.7 mm) stainless steel post body has a 2.10" (53.2 mm) long mounting surface for integration into Ø1/2" optical post assemblies via post contruction accessories.
Each VCP(/M) V-post band clamp includes one VCPL55 band for mounting components with diameters from Ø29.0 mm (Ø1.14") to Ø37.0 mm (Ø1.46"). Four alternative stainless steel bands, as well as a replacement VCPL55 band, are available separately below.

- Stainless Steel Bands for Use with V-Post Band Clamps
- Five Different Lengths for Components with Diameters from Ø0.47" (12.0 mm) to Ø2.09" (Ø53.0 mm)
- Each Band Engraved with Diameter Range
These stainless steel bands are used with the VCP(/M) band clamp to secure components of varying diameters. Each band is a different length to accept a different range of component diameters, with the allowed diameter engraved on the band. The minimum and maximum component diameters for each band can be found in the Band Specifications table in the Overview tab.
To exchange the band in a VCP(/M) clamp, loosen the band until the captive band interchange screw (5/64" [2 mm] hex) is visible through the release hole near the top of the clamp. Release and remove the band; take the new band of desired size and bend it such that the holes on either end of the band are aligned with each other. Insert the ends into the top of the clamp, align the holes with the band interchange screw, and then secure the band by tightening the screw. The band should feel loose when properly engaged by the interchange screw.
