Lower Clamp Blocks

Lower Clamp Blocks go inside or outside the Rocker box of a Truss Style Dobsonian Telescope. The Clamp Blocks that I make are similar to the Blocks made by Tectron except that they are made for 1 1/4" tubing and they bolt from the inside or outside. These Lower Clamp Blocks are CNC Machined from solid aircraft aluminum, then Black Anodized and UV Protected. The blocks are counterbored so that the tubes stop at the same depth to insure accurate alignment. A large wing nut is provided to lock the tubes in place.

The Blocks are sold in sets of 8 (4 lefts & 4 rights)
