String Retainer Block Template

Usually ships in 1 to 3 weeks


The String Retainer Block Template is what you'll need if you're using my String Retainer Blocks as an alternative / upgrade for individual string ferrules on the back of your guitar body.  Use your router to create a perfect pocket in the body for the retainer block. 

The small insert piece helps precisely locate the template on the back of the body by referencing the string holes. It is NOT used to make your own blocks.

Available in Several bridge types (string spacing). Requires a 1/2" guide bushing collar and 1/4" router bit (not included).

Please Note:

  • This item is the TEMPLATE ONLY! The blocks are SOLD SEPARATELY.
  • This template is for routing the pocket in the body, it is not for creating your own blocks.

1/2" MDF with engraved center lines and reference markings.

Router Guide Bushings 101:  A guide bushing mounts to the router's sub-base with a tube that protrudes below. A straight router bit extends through the tube. The outer surface of the tube rides against an edge guide or template, keeping the bit a set distance (offset) from the edge guide or template.

    String retainer is the bomb!

    Posted by Pete Weston on 2021 Nov 4th

    This was a Godsend, my drill press doesn't reach across the whole body of a Telecastet and I end up with wonky alignment of the holes. I have tried drillpress attachments for drills and they don't reach through the body, and drill guides just aren't the answer either. This is the best idea for keeping the string through body clean, aligned, and finished looking. Great templates again from Potvin!!!
