Dynapro / Blum - Maximum drawer width6/24
Does anyone know what is the max drawer width requirement when using either Blum or Grass Dynapro conealed drawer slides?
I use 1/2" thick drawer sides, so my O.A. drawer width is 3/4" less than the opening. This may change if your sides are thicker.
I've used the Blum with 32" wide drawers or so. They say at those widths you should be using the stabilization kit that you can purchase separately. I never do and they function well.
I think anything wider than 24" they want the stabilization kit.
I've done a 48" drawer and the only reason it was problematic was it's height made it a very heavy drawer, more than the normal slides could handle. I switched over to the heavy duties and it was better but you could still tell the hardware was struggling by the amount of sag at full extension.
Here's a blurb from Blum
The drawer I need these for is 55inch wide and 15inch deep with 3/4 inch base (it's a tray). It will hold only around 20kgs of weight excluding the base
The Salice "Shelf" drawer slide is designed for exactly what you describe. It installs much the same as a typical undermount but due to the design, additional slides can be added for wider pull-outs.
The Shelf slide is available in soft close or Push to open. There is also an optional "lock out" piece if that would be of interest. This might be used for a keyboard tray or retail showcases, for example. The Shelf slide is available in many lengths.
Here is a product bulletin for Shelf and a link for more information.
Shelf is available through any Salice distributor.
Best of luck,
