Petersen GT Turnbuckles

Petersen GT Turnbuckles

Petersen propose their unique GT turnbuckle body machined from naval grade, ultrasonically inspected aluminium bronze.

The innovative Petersen manufacturing process enables a 20% weight reduction, compared with the traditional method of forging a soft bronze to produce the desired shape, without compromising on strength.

Each body is individually hand polished and chrome plated to give an excellent finish.

Petersen manufacture all their own components with full traceability and accountability.

Material certificates and certificates of conformity are available on request.


Petersen GT Turnbuckles are available with multiple options for attaching to your rigging:

  1. Toggle and Swage Stud - Toggle Fork at one end for articulation (typically for attachment to chainplates) - Swage stud at the other end for professional swaging termination to wire
  2. Toggle and Compression Stud - Toggle Fork at one end for articulation (typically for attachment to chainplates) - Compression stud at the other end for DIY termination to wire
  3. Eye and Swage Stud - Eye at end - Swage stud at the other end for professional swaging termination to wire
  4. Stemball and Swage Stud - Stemball at one end (for attachment into terminal plate on mast) - Swage stud at the other end for professional swaging termination to wire
  5. Toggle and Fork - Toggle Fork at one end for articulation (typically for attachment to chainplates) - Fork at the other end for attaching to an eye e.g. already swaged on to the end of a wire
  6. Fork and Eye - Fork one end and eye at the other end
  7. Toggle and Blank - Toggle Fork at one end for articulation (typically for attachment to chainplates)- nothing on the other end



The Petersen design and manufacturing process has a uniform sizing convention.


The Petersen pin size is the smallest diameter hole that a Petersen pin will fit into.

The hole size is the largest diameter Petersen pin that will fit in the hole.

e.g. a 12mm pin will fit into a 12mm diameter hole and a 16mm hole will accept a 16mm diameter pin
