New 1/4"-20 Knurled Thumb Screw from Hejnar PHOTO

Hejnar Knurled Thumb Screw on LLSB R2
There are users of Long Lens Support Brackets, who own several long telephoto lenses, where the LLSB (Review) needs height adjustment to match the specifics of each lens.

Nevertheless, this adjustment can either be performed by a hex cap captive screw, as described in The basic Long Lens Support Bracket idea, or via the utilization of a small QR clamp acting as a regulator at the horizontal rail front end, as described in detail in the article Create a Heavy Duty Long Lens Support Bracket.

But some users are not so fond of neither method of making adjustments. Meaning, they do not like both hex keys and QR clamps.

In this respect Hejnar Photo has introduced a Knurled Thumb Screw in order to replace the hex socket captive screw for the vertical adjustment of their LLSB.

The Hejnar Knurled Thumb Screw has a quite large head with easy grip, which sports a narrower portion in order to fit into the LLSB captive slot groove. and a 1/4"-20 thread with a captive part.

The Knurled Thumb Screw fits into the LLSB's captive slot the same way as a regular 1/4"-20 captive screw, but its large knurled head allows for easy tightening by hand.
