What is the maxium weight force that can be applied to this opener?

I haven't measured the force, but it's considerable. I've got the 1-HP model on a poorly balanced, heavy, double-wide, swing door and the SOMMER grinds it open without issue. The specs call for a maximum of 100-pounds, and lists 33-pounds as "rated force", whatever that means. I recommend the opener.

Unsure, I would contact manufacturer. Although the garage door repair co. That replaced a broken spring said our double door was in the 90 percentile of weight in all the door she had encountered. The opener is slower than most, but makes up for it in torque.

The specifications are on the manufacturer website;http://www.sommer-usa.com/default.aspfor the 3/4 HP Max Force: 100 lbRated Force: 33 lbPower consumption: 150 wattsMax. Door weight: 550 lbremember the door spring is doing 95% of the work

All garage door openers require that the door be properly balanced by springs. This means that when the door is manually operated it requires no more than 20-30 #'s of lift. This operator is rated at no more than 525#'s total door weight that needs proper spring balancing.

I don't know the pounds of force, but I have forgotten I had these and pulled hard. They did not give at all. You have to use the magnet to open the cabinet.

It should only add 8 to 10 pounds overall, it has not shown any impact on the ability of the opener to operateA great deal and product

Not much at all. It has some weight obviously because it is meant to be strong. I would say maybe 2 lbs max if that

It's not that it's heavy. When fully extended the leverage given the extent of it means you need to move carefully and keep distance between your hands to control it. I do not lift it fully extended from horizontal, that would be a mistake. It is so sharp that cutting can proceed slowly and without jerking motions that would make it hard to control after a cut at its full extension. I am very happy and impressed with mine.

Oh Heck Yes. This opener is plenty powerful. I have a HEAVY 1960's era Wooden 16' x 7' door and it handles it like a champ. They don't make them much more powerful than this one. I am a picky buyer, and I absolutely LOVE this opener.

I have seen dual hinged garage door openers work with top mountings, so it could work in theory as the piece that anchors to the door moves a significant distance between the mounted engine and the actual garage opening. I would be sure to check the weight however as I'm not sure if this 1/2 HP motor is enough to move hinged doors (I don't know enough and if they use spring assist to lighten the load).

It should be fine. The only possible problem i see if if there are high winds the leverage might be an issue. This is a great opener. Might be smart to upgrade one model just to be safe...

The pull strength is not very strong. Will barely pull up a 16x9x3/8" thick plywood door. The motor switches on and off as it reaches a switch setting you can adjust.

Don't know the answer as my opener has only been used for 4 months. Works great still.

Ive never tested the absolute limits of this machine but You could fit 5 45lb plates on either side. Thats a lot of weight to lift. The cable is definitely strong enough and the pulleys seem adequate.

Hi Lorinda, I do not believe that this opener would work in that application unless the door drops directly from the bottom of the coup allowing the opener to lift verticaly as it is designed to do--Jon

If you have solid wood doors I would go with 3 hinges per door with the upper and middle closer together than the middle and lower. Can't say for sure pounds max, but there is a lot of force exerted on that top hinge. I tried them on a church door that had leaded glass window and it was too much for even the 3 hinge setup. Light weight or hollow door, 2 should work.

Instructions have a number (800)445-5262 or www.serius-strap.comThe door used to work from is probably going to be the limiting factor for weight

Depends somewhat on the weight of the window but about 15" at the max. In general, one arm of the opener is attached near the front of the window (opposite the hinge), and the other arm is attached to the wall of the structure just below. The opener pushes up the front edge of the window; it doesn't swing it open from the hinge. So the angle of opening will depend on the distance from the front edge to the hinge.

If you are able to push a button you can use this! It requires minimum strain and strength!

It will have no problem if you make sure that the spring that opens the door is set so it will lift the door.
