Ø1.5" Post Bracket Platforms
Posts & Bases Sold Separately
Adjustable Height Collar
Mounting Platform with Adjustable Height
The C1515(/M) and C1519(/M) Manually Adjusted Horizontal Mounting Platforms offer a generous array of 1/4"-20 (M6) mounting holes. When final positioning is achieved, the clamp locking mechanism is actuated with a quick-release handle. These platforms are a perfect alternative to our precision Lab Jacks when fine tuning of the position is not required.
The Quick-Release Handle is included with the C1515(/M) and C1519(/M) and is also available separately below. The handle allows for a simple and reliable way of securing these clamps to a post. It is 2.03" (51.4 mm) long and contains a 1/4"-20 (M6) threaded stud that engages the part by simply rotating the handle. Once the handle is tightened to secure a clamp to a post, the internal ratchet-type mechanism allows for the handle's rotational position to be adjusted without actuating the mounting stud. Simply pull the handle outwards to disengage it from the mounting stud then rotate it to a more convenient position. This feature ensures that the handle will always be accessible to the user.
The PSHA(/M) Adjustable Height Collar offers increased control over positioning. The PSHA acts as a fine height adjuster with a resolution of 0.025" (0.64 mm) per revolution of the actuator ring.
The C1515(/M) fits any Ø1.5" diameter post. The angle bracket provides an array of mounting options including seven 1/4"-20 (M6) mounting holes, two 1/4" (M6) clearance holes, and four 1/4" (M6) clearance slots. A quick-release handle [Item# C15QR(/M)] is used to secure the clamp in place once the desired height has been reached.
The height of the platform can be adjusted up or down within a 0.55" (14.0 mm) adjustment range by loosening the 3/16" (5 mm) cap screws connecting the bracket to the clamp.
Please note that posts are sold separately.
This manually adjusted platform is intended for applications that do not require the precision or flexibility of a laboratory jack. When locked, this platform provides a very stable 2.85" x 2.85" (72.4 mm x 72.4 mm) work surface.
One 1/4"-20 (M6) screw and a quick-release handle [Item# C15QR(/M)] are used to establish the platform height. The top cap screw is provided to add pre-tension. This allows the user to set how loose the clamp will be when sliding it down the post. The bottom handle is used to secure the clamp in place once the desired height has been reached.
Please note that posts are sold separately.
The PSHA(/M) Adjustable Height Ø1.5" Post Collar offers a convenient height adjustment for post mounted hardware. An easy-to-access actuator ring allows fine height adjustment at 0.025" (0.64 mm) per revolution. This collar also allows components to be freely rotated without changing height.
To use, slip the collar over a Ø1.5" post and hold at the desired height. Tighten the 1/4"-20 (M6) cap screw to secure the collar's position on the post via the flexure clamp. Place an optomechanic around the post on top of the collar and twist the actuator ring to adjust the component's height. The height can be locked by tightening the 8-32 setscrew with a 5/64" (2 mm) hex. The nylon ring on top of the collar prevents marring while adjusting the height.

The C15QR(/M) Quick-Release Handle provides a simple and reliable way of securing a flexure-based Ø1" (Ø25.0 mm) or Ø1.5" post clamp. In many cases a cap screw is used to lock a flexure-based clamp in place on a post, which requires a balldriver for adjustments. Depending on the mounted load, using a balldriver can be difficult, or even unsafe. This quick-release handle mitigates this problem by allowing the clamp to be hand-tightened, ensuring better control over the amount of torque applied to tighten or loosen the clamp. This also decreases the amount of time needed for basic setup and alignment by eliminating the need for additional balldrivers and allowing for a quick way to secure a clamp.
Easily installed by replacing the 1/4"-20 (M6) locking screw in a post clamp, the 2.03" (51.4 mm) long handle contains a 1/4"-20 (M6) threaded stud that engages a part by rotating the handle. Once the handle is tightened to secure a clamp to a post, the internal ratchet-type mechanism allows for the handle's rotational position to be adjusted without actuating the mounting stud. Simply pull the handle outwards to disengage it from the mounting stud, as shown in the image to the right, then rotate it to a more convenient position. This feature ensures that the handle will always be accessible to the user.
