Problems with full extension soft close guides8/27
When you go to pull on the drawer it drags a little at about 3/4 of the way out, it gets wobbly back and forth, and the soft close doesnt pull the box in all the way.
The box is built to right size - 1 inch from opening. The drawer is a bigger size drawer measuring 32 inches wide 21 inches deep and 3 1/2 inches tall.
The full extension soft close guides are made by hardware resources, and I mounted them to the back of the cabinets using the metal brackets.
I also checked the box is square, and the guides are the same distance in the front and back away from the side of the cabinet. (Parallel)
I dont know what to do to get these to work correctly, I put on a new pair of guides but it is doing the same thing.
Does anyone else have this problem, it seems to happen more on the wider drawer boxes. I would appreciate any help. Thanks
Having used several brands of side mount, full extension soft self close slides in the past many years - I have come to the conclusion that they are a PITA. They work when the clearances, sizes and weight of drawer are ideal. One thing slightly out of ideal and they get fussy.
I just ordered some Accurides, this week, to install in a tight, narrow installation that I cannot fit undermount slides in (I use Blum Movento usually). They are the newer design that came out last year, and I have not been to eager to try them... but in this case I have to.
They claim they are superior to the older blue ones, but I will let you know how it goes in a week of so.
Otherwise, I try and sell my customers on a regular side mount, or move to the undermounts which always work right for me.
If I remember correctly, all of the side mount, full-extension, soft-close slides that I used in the past needed 1-1/16" side clearance to work properly.
Put a straightedge on the drawer side. Likely a bow in the stock. Hand plane it flat and should solve the problem.
We tried the side mounts for a long time in all brands and there was always some that didn't operate properly. I've tried the newer versions...same thing, about 70% work correctly. We went to the Kv undercounts and all the problems went away. Under mounts are the way to go with soft close. I fought it for a long time, but they are the best.
It sounds like your problem is with the drawer width.
To my knowledge no under mount slide uses a 1” deduct to calculate the correct drawer width. Epoxy slides and most side mount runners use a 1” deduct but not under mount slides.
For any under mount you first must measure the thickness of the drawer side. Depending on this measurement, a specific deduct will be used to calculate the correct overall outside drawer width. Each manufacturer (Salice, Blum, Grass, KV and yes, HR) offer 2 models of under mount slides. One model is designed for drawers with side thickness of ½” to 5/8”. A completely different slide model is offered for drawers with a side thickness of ¾”.
For example: If your drawer side thickness is 5/8” (most common) you would deduct 3/8” (9mm) from the opening to get your drawer outside width. If your drawer side thickness is ½” then deduct 5/8” (15mm). If your drawer side is ¾” then you must use the slide designed for ¾” material and deduct 7/16” (11mm) to get your outside drawer width.
Below are two illustrations for the Salice Futura drawer slide calculations for both slide models. I am almost certain that your HR slides use the same calculations.
Best of luck
Since this is a reface, are you reusing the drawer boxes? If so, this probably means you are using side mount soft close slides. Have not recently tried any brands. I agree with Mark V. The old version Accuride worked okay, (not great) with an additional 1/16" clearance most of the time. The larger boxes are going to be problematic. If you read the specs for the slides, I'll bet your larger boxes are not within their range.
I will start switching over to undermount full extension soft close. Hardware resources has some at a good price has anyone use them? are they any good?
Is it worth paying the extra money for blum, or am I just paying for the name? I dont mind paying more as long as there is quite a bit difference in quality.
I just today replaced a couple of pairs of epoxy slides with KV side mount soft close. Except for this case, I exclusively use Blum Tandem undermounts.
For this job it was a budget thing to re-use the existing boxes. About half way though screwing around trying to get them to operated acceptably I thought I could have just about cranked out a couple of new boxes in less time!
I ended up having to belt sand the drawer boxes to get them a hair smaller, and on one I had to back off the center screw on the drawer just a hair. The box was apparently bowed a little - very possibly from my belt sanding. I got them to work OK, but never again!
Shep, I use only Blum so I can't comment on the others. To me it's not worth a few bucks to find out. If you've not used the undermounts, you'll be amazed at how forgiving they are. Even with the higher priced Blums they'll pay for themselves in labor savings setting them up.
We use the KV-GS4270 Side Mount Soft-close Slides with Great results on budget minded projects, Otherwise we use Grass Dyna-Pro's as they are smooth as glass
Side mounts suck in general (weather soft or not...though the soft have more issues) compared to the undermounts. Way more forgiving, way more consistent in action from drawer to drawer.
Hello, the general soft close drawer slides can be closed automatically when it is almost closed. As for the problem of wobbly back and forth, I believe it is caused by the problem of the working principle of the slides you use. Generally, this will not happen in ball guide rails. Or the position where you install the guide rail is a little inclined, which leads to wobbly back and forth. You can refer to vadania's soft closing drawer slides VK1245 and its installation video, and you can see the normal operation of a soft close drawer slides.
