Install LiftMaster 8500 Jackshaft Garage Door Opener

Показать описание

The LiftMaster 85000 Jackshaft garage door opener is made for residential and light commercial use. Install on sectional doors with torsion spring assembly only. In this video we are installing the operator on a garage door with high lift track and there is a beam located in the ceiling of the garage making it impossible to use a traditional opener. The wall mount design frees the garage of hanging openers and eliminates sound and vibration through the ceiling. MyQ enabled technology with an advanced wall console, (888LM) and programming ability for freedom and control. A remote light that can be installed anywhere in the garage. Must have at least 3" between the ceiling and the torsion bar. 8" between the side wall and the end of the torsion bar. Torsion bar must extend 1-5" past the bearing plate. Also need an electric outlet. This unit is battery back up capable, but the battery is not included. Before installing any opener. The garage door must be in good working order and adjusted properly. One disadvantage of this model is that a vault release or external emergency release mechanism cannot be used with this unit. Also costs a bit more than your standard type opener. Overall, a good solid garage door operator.

crazy question.. Do you know the distance measured from the top to the bottom mounting brackets on the sides of your 8500 opener box frame? I am working with the mounting bracket for the unit (3950MB) and cannot seem to find the measurements for the length between the mounting holes top and bottom and the width of the box itself. I assume it is 5.25" but nobody has any specifications that I can find. Could you measure yours possibly? thanks! Its a great video!

Can you add a 8500 opener to a ez set spring. If so the tortion sensor gets in the way of the door. Any ideas?

Hi Does your 8500 move a little as the door opens and closes?

Hi,

I just finished my installation but when the door opener is operating I can see how it is moving right and left with the shaft. I assume that the shaft moves because of the spring. Is this normal?
