The security services are responsible for all wrenches intended to access the opening of doorways, cabinet doors, manholes and the tightening and loosening of couplings, as well as hydrants and fire hydrants. 

Concerning the wrenches used to tighten the couplings, POK manufactures a wide range of them, which in general have the particularity of being made out of a non-sparking material such as copper-aluminum and aluminum alloy.

Steel wrenches

Wrenches made of steel have the advantage of being economical, which explains the choice of this material for the wrenches used to tighten Storz couplings in accordance with DN14822 for two versions, one for Storz DN52 and DN75, the other for Storz DN110, DN75 and DN52. In addition, when out of standard, wrench capacities can range from DN150, DN165, DN205, to DN250. POK’s range includes four chrome steel wrenches to equip mechanical workshops.

Their symmetrical couplings wrenches made out of aluminum alloy are particularly functional and elegant

Their symmetrical couplings wrenches made out of aluminum alloy are particularly functional, elegant and so ergonomic that they have been copied in Europe and Asia. They are available in three versions, for tightening couplings from 50 to 100, a second version for couplings from 100 to 150 and a third for couplings from 125 to 250.

Copper-aluminum wrenches

POK’s wrenches for couplings made out of copper-aluminum (anti-spark), cover versions for multiple diameters, including, in particular, the wrench intended for firefighters with multiple functions, including the 12 female squares for opening dry column valves, pyramid trunk squares from 5 to 8.5 mm for opening ventilation ducts and fire cabinet doors, female squares from 15 mm for hydrants, female triangles from 13 mm for opening fire hydrant boxes.

Aluminum alloy-made ‘Gung Ho tool’

A new range of multifunction wrenches, the ‘Gung Ho tool’ made out of aluminum alloy for one version and stainless steel for the other with the particularity of fitting in the chest pocket once folded, is suitable for uniforms without a belt. For information, the term ‘Gung Ho’ is a Cantonese term coming from Hong Kong and which in English applies to a strong and energetic character.

Other products have a specific use, for example for watering nozzles. POK also build wrenches for British BSRT couplings, for American couplings according to the US aesthetic. Their range also includes wrenches for American and French hydrants and fire hydrants.
