How much do you need your drawer to open? Drawer extensions come in three options3/4 extension, full extension, and over travel.

You are probably familiar with the 3/4 extension, as they are the typical choice for many pieces of office furniture. With the 3/4 extension, part of the drawer remains inside the cabinet when opened. This is an economical choice and comes in many mount styles.

When using the full extension slides, the drawer can be extended out to expose 100% of the drawer. This is also sometimes referred to as full access.

Over-travel allows the drawer to open beyond the full extension. This is desirable if there is a lip or extension on the desk or countertop that prevents full access to the drawer with only the full extension slides. These are also typical for large filing cabinets.
