34321
The spring shares the same footprint as the original 34309 hinge. The advantage of the new 34321 hinge is that it has an integrated Soft Close mechanism ensuring a very quiet and controlled closing. Just like the 34309 hinge this new hinge has an adjustment screw that helps regulate the opening angle but this new hinge also has a 2nd screw that helps regulate the force of the opening / closing. The 34309 hinge has been in the marketplace for many years so this new spring should prove extremely popular.
