Understanding Duraslide Drawer Slide Load Ratings

When it comes to drawer slides, numbers like 45kg, 125kg, or 227kg can sometimes be confusing. To help clarify, here’s a simple guide on how Duraslide Drawer Slides handle weight and how to make the most of their load capacity.

What Does 227kg Mean?

A 227kg rating refers to the maximum static weight a drawer can safely support when fully extended. This includes not just the items inside, but also the drawer itself—including the materials used to build it.

Duraslide does not provide weight ratings for different positions along the drawer’s travel, and we don’t specify how much weight can be supported at the front versus the back. There are simply too many variables—drawer length, materials, load distribution, and usage patterns—to make such guarantees.

Tips for Safe Load Distribution

While we don’t provide exact breakdowns, these best practices will help you get the most out of your Duraslide slides:

1. Distribute Weight Evenly
   Whenever possible, spread items across the drawer. If heavy items must be concentrated, place them toward the back—this is where the slides provide the strongest support.

2. Keep Loads Secure
   Loose or rolling items can put extra strain on the slides and locking mechanisms, potentially affecting performance.

3. Avoid Continuous Full Loads
   Although a drawer can support its maximum rated weight, leaving it fully loaded in the open position for hours or days may affect performance over time. Duraslide slides are designed for normal, intermittent use—opened and closed regularly rather than left under constant load.

Following these guidelines ensures your Duraslide drawer slides remain reliable and long-lasting.
