The 1/4" (M6) counterbored holes can be used to elevate rails above a breadboard.
  • Mount 34 mm Rails to Any Breadboard with 1/4"-20 or M6 Taps
  • Two Counterbored Holes for 1/4"-20 (M6) Cap Screws
  • Slide Along Rail Prior to Lockdown
  • Ideal for Attaching PostsPost Holders, or Pedestal Posts
    to a 34 mm Rail
  • 1/4"-20 (M6) Tapped Hole Provides Side Mounting

The XT34HP(/M) Dovetail Mounting Clamp allows 34 mm optical rail constructions to be mounted on top of a breadboard or other 1/4"-20 (M6) compatible optical assemblies. It contains two 1/4" (M6) counterbored holes and is post mountable by the single 1/4"-20 (M6) tapped hole on one side. When flipped, the the counterbored can be used to attach various optomechanics, such as posts, pedestal posts, or post holders, as shown in the image to the far right.

The spacing between the counterbores, which is either 1" (25.4 mm) or 25 mm, is specifically designed for direct compatibility with either imperial or metric breadboards.

  • Four Bottom-Located M3 Counterbored Holes for Vertically Mounting 34 mm Rails
  • Holds Position of Rails During Initial Setup Process
  • Relief Cuts in Base Provide Excellent Stability

This magnetic base has four bottom-located M3 counterbores for vertically mounting 34 mm rails on an optical table or breadboard. The two rare earth magnets on the underside of this anodized aluminum base provide the ability to temporarily secure 34 mm rails during the initial setup process. The force from these magnets is strong enough to help prevent accidental movement of the vertically-mounted rails, while still allowing for easy repositioning. Once all positioning adjustments are complete, the base can be secured to the optical table or breadboard using the two 1.25" (32 mm) slots.

This base also has three bottom-located 1/4" (M6) counterbored holes for mounting our Ø1/2" Post Holders.
