For installation or removal of thru-hulls that have two appropriate lugs in the passageway. The tool can be used to conveniently hold the bushings in place when tightening or loosening the locknut. The tool can also be inserted from the inside, so that a second person is not required to hold the thru-hull fitting from the outside during installation or removal.

Material: galvanised steel

Important: The inside diameter of thru-hull fittings may differ due to material thickness and manufacture. To ensure that the tool can be inserted, the inside diameter of the diffuser must be known and correspond to the outside diameter D of the installation tool specified in the table.

Installation wrench for TRUDESIGN through hull
Practical installation wrench for all sizes of TRUDESIGN through hulls. TRUDESIGN is the world leader in fittings made from composite materials. From its founding in 1974 the fittings are manufactured in New Zealand. Every TRUDESIGN part is made from high tensile composite GRP, a glass fibre reinforced Polyamide. The advantages are a high rigidity, temperature-resistance -40° to 80° C, resistant to oil and chemicals, of low weight, absolutely corrosion-resistant, electrically non-conductive and therefore especially suited for ship building materials which are galvanically sensitive like aluminium and steel. Every TRUDESIGN fitting has a tapered Whitworth pipe thread BSP (British Standard Pipe Thread) according to ISO 228-1, it is therefore fully convertible with fittings from brass, bronze or stainless steel. The shuttle valves and through hulls are approved and IMCI certificated after ISO 9093-2 (sea cocks and through hulls for pleasure vessels).
