LiftMaster

Q: Is this compatible with new B1381 Chamberlain led opener?

Yes it is. I purchased the B1381 in Dec 2019 and it has the security shield symbol on the cover ( it is a shield with half light and half dark divided diagonally). It also has two lock connectors on the unit next to the up and down adjustment buttons close to where you connect the wires for the sensors and control panel and the WiFi learn button. Since it has two lock connectors if you want you can connect two of these locks, one on each side of your door.

Q: Is this compatible with Chamberlain openers?

It is compatible with at least some some Chamberlain openers. Liftmaster and Chamberlain are the same company. To know if yours is compatible the two requirements are for it to have the shield symbol on the cover and for there to be two lock connectors on the unit next to the up and down adjustment buttons. I have the Chamberlain B1381 and it is compatible.

Q: Wiil this work on the Chamberlin B970?

NO, this will not work with the B970

Q: How far does the box protrude laterally from the track? (e.g. what is the length of the plastic box with the bolt retracted?)

The box protrudes 7.200 from track. when in locked position the bolt protrudes .800 from inside surface of track
