The EQ6Rail is our successor to the MkIII EQ6Wedge – built on years of customer feedback, with a much simpler, more direct and precise method of adjustment. Because of its efficient design, the EQ6Rail is also more easily fitted and cost effective.


Q) How does it work?

A) Instead of the tip of the bolt hitting the metal tab in the mount at an increasingly acute angle with rising latitude (and bending), there’s a large curved surface which rises on the sloping base, to always maintain the optimal contact angle with the tab. The other bolt just locks the adjustment, as normal.

The result is a direct transfer of the adjusting force across the face of the tab, instead of at a point, and the adjusting bolt is supported at two places, so doesn’t need to deal with any bending forces. Backlash is minimal as all points of contact are loaded and forces are in one plane.

Range of operation is approximately 15 – 75 degrees in Latitude

Q) How does it attach to the mount?

A) The cutaway picture (image 2 of 3) shows the EQ6Rail located within the mount head. It’s shaped to closely fit and be retained by the internal mount structure and the forces on it. It’s also possible, but not necessary, to use double sided tape, mastic or adhesive – as with the EQ6Wedge.

Q) How does the EQ6Rail differ from the EQ6Wedge?

A) By simplifying the design as much as possible, the EQ6Rail avoids the external knuckle joint and screw assembly which drives the adjustment of the EQ6Wedge. It also avoids problems with slip when certain  bolts are not properly and carefully adjusted. Because of its evolutionary process, you could even characterise the EQ6Rail as a MkIV EQ6Wedge……..


The EQ6Rail Kit Contains:

  • 1 x Rail Wedge Base
  • 1 x Slider Block
  • 2 x Alloy engraved caps (one indexed for left side)
  • 4 x Adhesive Strips
  • 1 x Grease and applicator

Instructions to fit the EQ6Rail will be sent with your purchase.

You will need

  • 2 x 16mm or 17mm Spanners – varies with sample
  • M2.5 Hex Allen Key
  • pt Pozi/Phillips Screwdriver
  • Flat bladed screwdriver or similar
  • Flat working surface as it’s easier to remove the base when the mount isn’t on the tripod

If your adjusting bolt is already bent please let us know and we’ll source a cheap replacement for you.
If the adjustment tab in your mount is scored or rough, it’s advantageous to smooth it for better operation.

For those of you with lighter setups, particularly if you live in the Southern half of the country, the EQ6Bolt may be all you need.

Please bear in mind that the slider is not fully captive, so if after assembly you decide to remove the bolts, either wholly or significantly and disturb the mount, the slider can come away from the block and may be difficult to put back without disassembly and reassembly.

    I’m highly delighted with this. At last I can polar-align my NEQ6 laden with 10″ SCT plus extras by using normal turning pressure on the alt. bolts without having to use both hands – in fact, thumb and forefinger is fine. This means that the mount can be securely locked in the correct position quickly and easily. Instructions are a little sparse. Highly recommended and like having a new mount without feeling as though you’re wrecking it with every turn of the alt bolt.
