Bullet hinges are great hinge options when you need something compact and narrow when space is limited. These are commonly known as 'lift-off hinges' because they are easily detachable by, what the says, lifting off one half of the hinge. The only issue you'd probably have trying to lift them off is when it is already welded to gate because you'd then need to make sure that you can shoulder the gate's weight. 

Our bullet hinges come in different lengths and washer sizes, and can withstand different weights. Aluminium, steel and zinc-plated are the materials it comes in. We also provide a marine-grade option.
