Overhead Storage Bin Gas Spings

[crazydog]

I need to replace all six of my Gas Springs for the overhead bins in the living area of the coach. My online searches have come up with no information on a replacement. I have called several different places and no one has a cross reference. If you have replaced yours, what lifting force did you use?

For reference, these are labeled as follows.

Gas Spring Company
Colmar, Pa.

F1921

112 1

Each end attaches to a ball mount. The extended length is 12 inches from center of mount to center of mount. The collapsed length is 8 and 5/16 inches from center of mount to center of mount.

I believe the gentleman from Orr and Orr stated the lowest lifting force he had was 35 lbs. That seems way too high for such a light door. Also, his collapsed length was 8 and 1/2 inches, which I was unsure if the door would close.

Thanks in advance for any information you have.

I ordered Gas Springs for all the doors on my 84 ½ PT-36 back in 2001 from Orr & Orr.

For what it’s worth, here's the Part Number that I ordered for the inside overhead storage cabinet doors (they worked fine):

H9412-35 (35 Lb)

On a fish scale, the doors weigh 3 to 4 lbs. I don't know how they calculate what to use, but it would seem 35 lbs would be too much.

Your wife might not think so if you are driving down the road and she opens one up to get a blanket or a pillow and you hit a bump. At the 35 lb rating it may save her from getting knocked on the head. Just sayin'

My guess is that you're not taking the "leverage" factor into account. The gas spring attaches close to the hinge -- it takes a lot of force to push a door up and hold it open from that attachment point.

As a test, remove a gas spring and try lifting the door from the gas spring's attachment point.
