How is the weight limit on drawer slides figured?

a) centered with drawer closed (artificially high), or
b) on leading edge at full extension (unlikely), or
c) in between -- but where/how?

I assume it is done by determining the weight needed to cause failure and backing off by a comfortable margin.

Hi bkorb,

Most manufacturers of kitchen cabinets and most furniture manufactures do not place weight ratings on drawer slides. The hardware strength is based on the expected use and the weight of common household items. These ratings are determined and specified when the product is designed.

For industrial slides such as those used in tool boxes or commercial applications drawer slides are rated by two different methods static (non-moving) and dynamic (in motion).

For static testing a specific weight is placed in the drawer and the sag is measured, in dynamic testing the same amount of weight is placed in the drawer and the sag is measured after the drawer slides has been cycled a certain number of times, in most cases the number of cycles of the slides expected life, 50,000 to 100,000 cycles.

The Kitchen Cabinet Manufacturers Association tests drawer slides with a 15 pound load and operates the slides to test for durability and load handling capabilities. The drawer slides we sell at the Home Depot are designed to meet or exceed these specifications.
