Snap-on Rolla-bench Tambour Stuck

[ipd72]

Hi there. I recently bought an old Snap-on KRA-300B, and the tambour door is stuck up in the top. The pocket it recesses into is not accessible by removing the top drawers.

Does anyone know how to unjam those tambour panels?

What one looks like:






Sorry no info on un-sticking it. Is it locked?

I would start by completely removing all the drawers. Do you know how to remove drawers? You need to pull out the spring clip on the side on each drawer. If you don't have the SO tool you can use feeler guages or a chunk of hack saw blade. You can also get these tools on Ebay. Once it's 100% hollow you should be able to see what's going on and figure out the next steps.

Yes, I've figured out how to get the drawers removed - turns out electrician's fishtape works really well.

As far as I can see, the tambour door doesn't go all the way down the back, I think it's just in the top. But like I said, there's no access to the top unless I cut it open.

I remember doing this a while ago. Remove the rails along the sides is a starting point. Which door do you have painted or the aluminum one?

 

[ipd72]

I think it's aluminum. The rails in the front (the only ones I can access) seen to be riveted on:

Have you tried opening it upside down, shaking it aggressively or spraying penetrant in the channel? Something could be lodged in the channel.

I removed those rails and took the door out to inspect.

Do you mind elaborating?

Pretty sure this thing weighs 200+ pounds. I cannot shake it aggressively.

That's what big dead blow hammers are for. A few whacks might free up what's keeping it stuck.

 

[ipd72]

I do have one of those. I'll give it a go.

Can you please say more about how you took the rails off?

 

[FJ 432]

What I recall is that there are 2 screws each that hold the rails to the side. once off you can disassemble the tamboor door.

does your box have a square hole in the back, about 6" x 6", that may have a cover and/or also an power inlet, and a place where a small lamp came out of?

I you have that hole, and its covered, remove the cover and have a peek in that way.

I have removed and stripped and repainted my tambour, and I vaguely remember mine being caught up just as the tambour curves off the inside top to head down into the back.

The PB Blaster company I believe also sells a garage door roller lubricant, some of that might be good for the tambour door.

My Liftmaster bellcrank garage door installer said to use a product like that a couple of times a year, and that your door will lead a long, happy life. Spray it liberally on the track and the rollers and then operate the door open/closed. I do it when the clocks change time.

If I could get to the tracks and the tambour door itself, I would follow these instructions. As it stands, I can't access either.

It has a square hole on the right side, which from photos in a 1970 product guide could have had a juntion box in it. However, it doesn't grant any access to the tambour door or its tracks.

So your picture of the side rails would indicate that instead of screws (which were a part of mine) you have a rivets securing your rails. I would drill those out. Removing the rails allows you to remove the door. You could pop rivet them back in place once you solve your issue.

Sorry, I didn't see your photo earlier.

On some of those doesn't the top front flap need to be pulled up a bit otherwise it acts as a latch for the roller door?

 

[Oldtuleguy]

Yup you have to pull it up
