The Korena take

Locking Tune-o-matic and stopbar set in black for metric large-post guitars. For owners of metric-spec instruments whose bridge shifts during restrings.

Strong match

Who this is for

  • Metric-spec guitars with large posts and roughly 74mm stud spacing
  • Black hardware builds where chrome or nickel would look wrong
  • Players who pull the strings off completely and lose saddle position

Consider the trade-offs

When to look elsewhere

  • Imperial small-post guitars — the studs will not fit the holes
  • Anyone needing only the bridge; the bridge-only version costs less
  • Players wanting aged or nickel hardware to match older parts

What matters in use

The specifications, translated

Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01

2.913 in hole-to-hole spacing

About 74mm centre to centre, the metric layout. Measure your existing posts before ordering; a few millimetres out is unusable.

Detail 02

.436 in post diameter

Roughly 11mm, the large metric post. Small-post guitars need the standard version instead — there is no shimming this.

Detail 03

.250 in hole diameter

A quarter inch through the body. Compare against the holes already in your top before committing.

Detail 04

.421 in bridge height

A low-profile bridge body. Combined with post height, it sets how far your action can actually drop.

Detail 05

.545 in bridge width

Front-to-back footprint of the bridge. Worth checking if a pickup ring sits tight against it.

Detail 06

Black finish

Coated rather than plated bright, so it shows scratches at the saddle slots more readily than nickel.

Final check

Know before you order

  1. 01Confirm your posts are metric large-diameter, not imperial — the two never interchange
  2. 02Restringing is a full teardown; budget for new strings and a setup
  3. 03A hex key drives the lock screws once the parts are seated

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01How do I know if my guitar is metric?

Measure the post diameter and the centre-to-centre spacing. This set wants roughly .436 in posts at 2.913 in spacing. Imperial guitars use noticeably thinner posts.

02Is the tailpiece included?

Yes. The set covers both the locking Tune-o-matic bridge and the locking stopbar tailpiece with their studs.

03Will the black finish wear off?

The saddle slots and any point where a string crosses the bridge will show wear soonest, as with any coated hardware.

04Can I install this myself?

It is a strings-off swap using a hex key. The harder part is resetting intonation and action afterwards, which needs a tuner and time.
