Topic tags/keywords: draw slides drawers hardware

I’m installing slide out trays in the cabinets of our travel trailer so the DW can more easily get to cooking items. The problem I am having is that the left side of the trays, 3 in all, sticks out 1/8” to 1/2” further than the right side of tray when pushed in all the way in. I cannot figure out what to adjust to get the tray to slide in square.

I am using KV 8400PR slides with the back bracket. The trays/drawers are 16 inch front to back 15.5 inches left to right and 3 inch up and down. The wall and the slide mountings are square, as are the slide mountings & face frames. Both slides are the same distance above the bottom of the cabinet. I use blocks cut to length to locate the slide. The drawer attachment is the same on both sides of the tray. The slides are equal distance apart front and rear. The cabinet openings are square.

I have spent 3 days trying to figure this out. I have e-mailed KV but they could not help. I’m at a lost and it is about time to go camping. Without my DW’s cabinets being complete I can’t go trout fishing. I need some help badly.

Thanks Guy Woodguy

sounds like you checked all the likly suspects, how about the distance from the front edge of face fame to front of the cabinet member part of the slide, are they equal on both sides?

It sounds like your drawers are not tracking perpendicular to the face of the cabinet. Can you shim the back side of the piece that attaches to the cabinet on the side that protrudes? This may help, but may also cause some binding when you try to close the drawer.

Are the trays themselves square? Just a thought.

You mentioned a bracket at the back, is that holding up the rear end of the cabinet member? can you loosen the back bracket screws , push the tray in where you want it and then tighten the screws for the rear bracket? The nylon sockets we used to use for Blum slides had elongated holes to provide some adjustment.

Have you tried forcing the slightly open side closed? I find with those types of slides that the two sides can get out of alignment front-to-back when you first install the tray. This usually leads to the situation you are describing, but by forcing the slightly open side all the way closed, the two slides end up back in alignment.

With side-mounted ball-bearing slides each slide has two members that are at play: The cabinet member, which is screwed to the cabinet sides on frameless cabinets, or to the face frame and on a rear brackets on a framed cabinet. The other member at play is what is called the drawer member. If the tray or drawer is square, then either a cabinet member is mounted too far forward on the cabinet, on the drawer member is mounted too far back on the drawer box on the side that is sticking out. 1/2” is a HUGE disparity.

One thing that the instructions on these type of slides never tell ya is that the drawer member shouldn’t be installed flush against the back of an applied drawer front. Make sure to mount the drawer member 1/8” or so behind the drawer front. They need this gap in order to allow the detent bumper room to do its thing.

Lastly, make sure both members are fully engaged. I’ve had some of these feel secure, but they weren’t properly latched together.

Good luck. Scott
