Products -> spring hinges -> HAWGOOD type 4140K

HAWGOOD spring actuated hinges are designed for use where self closing, swing door operation is required. For example; schools, hospitals, offices, warehouses, shops, factories and public buildings.

This type comes always with 90 stop and offers very good accessibility by using light springs.

The simple but solid construction of these spring hinges allow an opening angle of ca. 95 on both sides. (Doors that can be opened further need to be limited by e.g. a door stop).

The form of the synthetic material shoe results the door to swing only shortly and is kept firmly closed. As the door, whilst opening, turns away from the frame-post, the inclination seams with the closed door is minimum and the free passage with opened doors maximum.

A set of spring hinges type 4140K is suitable for doors with a maximum door weight of 45 kg. and a maximum door width of 93 cm. For heavier of wider doors we advise you to use type 4241. (See also the table on the fitting page).

To counteract the difference in loads between the top and bottom hinges of the door, always mount the type 41 hinge (gray tube and strong spring) to the top of the door.
