Adjust or replace hinges

Sorry, there is no adjusting these style hinges, they are welded in place, you can usually make them better by replacing the pins and bushings in the hinges but if the hinge itself is wore that bad where bushings wont fix it you're looking at having a body shop weld new hinges in...

A familiar example of what hinges do, are the hinges that are attached to a door.

No door hinges and cabinet hinges are two different things. Door hinges are generally much larger than cabinet hinges.

Cabinet hinges and door hinges are not at all the same. They are different sizes and can withstand different amounts of weight.

The main types of door hinges are barrel hinges, butt hinges, and concealed hinges. Barrel hinges and butt hinges are used on doors while concealed hinges are usually used on furniture such as cabinets.
