Sizing Guide 

To ensure a secure and precise fit, it’s important to measure your binocular housing correctly before selecting a size.

What you’re measuring:
The outside diameter of one barrel (the main tube of your binocular), not the objective lens or eyepiece.

How to measure:

1. Use digital calipers for the most accurate measurement (recommended)
2. Measure the outer diameter of the barrel at the location where the clamp will sit (choose a location that is at least 18 mm wide, which is the width of the clamp).
3. Take your measurement in millimeters (mm)

Choosing your size:

• Select the closest matching size to your measurement
• Our clamps are available in 0.5 mm increments (50–70 mm) for a precise fit
• If you're between sizes: Round to the nearest available size.
  • Example: 
  • If your barrel measures 56.1 or 56.2 mm, choose a 56 mm clamp.
  • If your barrel measures 56.3 or 56.4 mm, choose a 56.5 mm clamp

Installation 

1. Set Your IPD (Eye Width): Adjust your binoculars to your normal viewing width. This ensures the clamp can be installed in the correct orientation for level viewing.
2. Install the 1/4"-20 Insert: Slide the 1/4"-20 threaded nut into the slot on the clamp base
3. Install & Align the Clamp: Slide the clamp around one barrel and align it horizontally. Using the 2.5mm allen key, tighten until snug - do not overtighten. The clamp should not rotate or slide.
