Pedestal Base Adapters

Click to Enlarge
Three SCF1 clamping forks hold three space-saving pedestal base adapters in close contact, providing a platform for mounting posts with only 1" center-to-center separation.

• SBE1(/M) and SBE2(/M) Adapters Convert Ø1" Posts to Pedestal-Style Mounts
  • SBE1(/M): 8-32 (M4 x 0.7) Threads
  • SBE2(/M): 8-32 (M4 x 0.7) and 1/4"-20 (M6 x 1.0) Threads
• Space-Saving Ø1" (Ø25.0 mm) Bases Support Mounting Optomechanical Components in Compact Setups
• Ø0.13" (Ø3.2 mm) Torque Hole for 7/64" (2.5 mm) Balldriver Provides Extra Leverage During Tightening

The SBE2(/M) adapter can be flipped to utilize either the 8-32 (M4 x 0.7) mounting threads (left) or the 1/4"-20 (M6 x 1.0) mounting threads (right), as shown here.

The SBE1(/M) and SBE2(/M) Ø1" (25.0 mm) Pedestal Base Adapters are machined from non-magnetic 303 stainless steel and offer a low-profile option for mounting our Ø1" pillar posts, fixed lens mounts, Ø1/2" post holders, and any other optomechanical components that are compatible with either 8-32 (M4 x 0.7) or 1/4"-20 (M6 x 1.0) threads. They feature a Ø1" (25.0 mm) base that does not extend beyond the diameter of our Ø1" pillar posts and are designed to be held securely to a breadboard exclusively by our SCF1 Compact Clamping Fork, making them ideal for applications where table space is limited (see photo to the right).

The SBE1(/M) pedestal base adapter is 1/2" (12.5 mm) long and features an 8-32 (M4 x 0.7) tapped thru hole for directly mounting an 8-32 (M4 x 0.7)-threaded Ø1" pillar post via an 8-32 (M4 x 0.7) setscrew (such as Item # SS8S050 (SS4MS12)). The SBE2(/M) double pedestal base adapter is 1" (25.0 mm) long and features 8-32 (M4 x 0.7) internal threads with a depth of 0.30" (7.6 mm) on one end and 1/4"-20 (M6 x 1.0) internal threads with a depth of 0.38" (10.2 mm) on the other. With a pedestal base on both ends, the double pedestal base adapters can be flipped upside-down depending on which thread size is needed, as shown in the photo to the left. In addition to the 8-32 (M4 x 0.7) mounting options mentioned above, the added versatility of the 1/4"-20 (M6 x 1.0) threads enables direct mounting to 1/4"-20 (M6 x 1.0)-threaded Ø1" pillar posts or our standard Ø1/2" post holders via a 1/4"-20 (M6 x 1.0) setscrew (such as Item # SS25S050 (SS6MS12)).

Each of these pedestal base adapters also has a recessed Ø0.65" (Ø16.5 mm) central pillar above the 0.20" (5.1 mm) thick base, providing a clamping surface for the SCF1 clamping fork. All space-saving pedestal base adapters can also be mounted directly to a breadboard or optical table using the aforementioned setscrews.

The BE1R has a magnet in the base for stability in temporary setups.

A CF125 fork is used to secure a Ø1/2" post holder to an optical table with a BE1 base.

• BE1(/M) and BE1R(/M) Adapters Convert Standard Ø1/2" Post Holders and Ø1" Posts into Pedestal-Style Mounts
• Clamping Fork or CL8 Table Clamp Secures Base to a Breadboard or Table
• 1/8" (3 mm) Hex Socket on Bottom for Tightening
• Machined Bottom Relief Cut for Added Stability
• BE1(/M) Adapter Available in Packs of Five

The BE1(/M) and BE1R(/M) pedestal base adapters feature a 1/4"-20 (M6)-threaded stud that fit into the bottom of our standard Ø1/2" post holders or Ø1" posts to convert them into pedestal-style mounts for added stability. The BE1R(/M) adapters have a magnet in the base that is sufficiently strong to securely hold the base in place without clamping to an optical table (see photo to the right). Made from solid 303 stainless steel with a 1.25" (31.8 mm) outer diameter, this adapter allows standard Ø1" posts to be used with clamping forks, and can be tightened onto the post or postholder using a 1/8" (3 mm) hex or ball driver.

The BE1(/M) is available in a pack of five for ease of ordering.

The PF175B fork is used to secure a Ø1.5" post to an optical table with a PB4 base.

A Ø1.5" post is converted to a pedestal-style post with a PB4 base adapter.

• Mount 1/4"-20 (M6) Tapped Components in an Arbitrary Position 0.24" (6.1 mm) Above the Breadboard
• PF85B, PF125B, or PF175B Clamping Fork or CL8 Table Clamp Secures Base to a Breadboard or Table
• 1/8" (3 mm) Hex Socket on Bottom for Tightening
• Machined Bottom Relief Cut for Added Stability

The PB4(/M) and PB4R(/M) Ø1.85" (47.0 mm) pedestal base adapters feature a 1/4"-20 (M6)-threaded stud, which fits into the bottom of our Ø1.5" posts to convert them into pedestal-style mounts. They are manufactured using solid 303 stainless steel with a 1.85" (47.0 mm) outer diameter. The PB4(/M) can be tightened onto the post or postholder using a 1/8" (3 mm) hex key or ball driver, while the PB4R(/M) has a 3/16" (5 mm) hex socket. The PB4R(/M) adapter also has four high strength magnets in the base (seen in the family image above) that are sufficiently strong to securely hold the base in place without clamping to an optical table. To secure the base, a CL8 table clamp or a PF85B, PF125B, or PF175B clamping fork (shown in the photo to the right) can be used. However, using these items will restrict the width of the component being mounted to a maximum of 1.5".
