Petersen Stainless rigging screws feature generously proportioned toggle straps which are designed to take the full wire breaking load on each side of the eye and pin. This avoids the issue of premature failure due to transient unbalanced loads.
This Petersen rigging screw design incorporates the Gracilis body - a unique design offering strength and integrity.
Traditionally, turnbuckle bodies are manufactured by forging a soft bronze to produce the desired shape.
This unique Gracilis design allows the bodies to be machined from high grade materials, and for the weight to be reduced by 20% with no adverse impact on strength.

NOTE: Petersen Stainless use the following convention throughout their range – the pin size is the smallest diameter hole that our pin will fit into, the hole size is the largest diameter pin that will fit in the hole. For example, if we list a pin as being 12mm then the pin will fit into a 12mm diameter hole and conversely if we list a hole as being 16mm then a 16mm diameter pin will fit in the hole. If in doubt please ask.
