Control Board, Easy Read Diagnostics - The LED light diagnostic on the control board permits easy diagnostics of problems or missing connections. This allows efficient repair and swift continuation of normal electric gate operation.
Soft Start/Soft Stop - Soft start/soft stop is a feature in which the control board, during the set up process, learns where the opening and closing points are for the swing of the gate. Then during normal operation the gate operator automatically slows the motion of the gate to smoothly meet with the gates destination point. This reduces stress on the gate and operator for extended functionality.
Bi-Part Latch - Designed to allow one gate leaf to begin opening or closing independently for those gates that have overlapping leaves.

Words from Senior Application Engineer Anthony Geato
“The LiftMaster LA400 and LA400 Dual plug in gate openers are rated by Gate Crafters for gates between the lengths of 10 and 14 feet. This kit includes your choice of control box enclosure as well as your choice of transmitter.
The arm on the LiftMaster LA400 features a lockable release that allows you to unlock the arm and manual operate your gate. The motor on the LA400 is approximately 2 and 1/4 inches in diameter and about 4 inches in length. The worm drive transmission on the LA400 features gears that are made of stainless steel and brass. This transmission spins a shaft that controls both the limit switches and screw drive. The shaft that spins the screw drive rides on sealed ball bearings. This gate opener has 3 limit switches. Two of the limit switches tells the control board when the arm is either in the open or closed position and the 3rd limit switch tells the gate opener when the gate is unlocked. One downside of this type of limit switch, is that they are prone to contamination. At some point in time, these limit switches may need to be replaced due to dirt getting inside of them.
The LiftMaster LA400 is available with your choice of control board enclosures. The larger control board enclosure can house a larger battery and is easier to wire. The larger control board enclosure can hold two 12 amp hour batteries, which you provide. The standard control board enclosure comes complete with 2 7 amp hour batteries. Each enclosure comes with the same control board, that has all the necessary plugins for the accessories you wish to use. This control board is compatible with various accessories such as: exit loops, locks, entry devices, safety devices, exit wands, and edge devices.
Gate Crafters gives you the option to choose the transmitter that you want. When you order your LiftMaster LA400 from Gate Crafters, you have the option of choosing either LiftMaster transmitters or Estate Swing transmitters. When you choose the Estate Swing transmitters you will be able to easily add on other great inexpensive Estate Swing accessories such as wireless key pads. Also the Estate Swing transmitters are less expensive than the LiftMaster transmitters. We have also successfully tested the Estate Swing transmitters up to 1400 feet away from the receiver.
I started Gate Crafters in 2002 with the goal to provide my customers with high quality gate opener and gate opener accessories. Gate Crafters has technical support 7 days a week from 9 am to 9 pm, eastern time. When you are buying your gate opener, our experts can help you put together a complete package so your gate operates the way you want it to. So please give us a call, send us a email, or use our live chat and we are more than welcome to help you out. We look forward to hearing from you."
I bought the opener to install on my one of my costumer's gates that we built for their home. I was a little paranoid when she and her 2 year old son came out and watched the whole setup process. But, to my surprise, this was the first opener I have installed and it took no time at all to get it fully operational. The manual was very easy and it just took a few steps to set it up. It is working great now.
Thanks, LiftMaster and the people at Gate Crafters. You made my life easy with the ease of ordering and install.

Words from Senior Application Engineer Anthony Geato
“The LiftMaster LA412 and LA412 Dual solar gate openers are rated up to 850 pounds or gates up to 16 feet in length. The LA412 kits come with your choice of control board enclosures, a 10 watt solar panel, and your choice of transmitters. LiftMaster gives the LA412 a 2 year warranty.
The LA412 has a lockable release that allows you to unlock the arm, so you can manually open your gate. The motor on the LiftMaster LA412 is about 2 and 1/4 inches in diameter and about 4 inches long. The worm drive gear transmission is made up of stainless steel and brass gears. The gear transmission spins a shaft that both controls the screw drive as well as the limit switch system. This shaft is riding on sealed ball bearings. This gate opener has an additional limit switch that tells the gate opener, that the gate has been unlocked. This is a well made gate opener, with the only exception being that the limit switches are electric and not magnetic. This type of limit switch is prone to contamination and may need to be replaced at some point in time.
The LiftMaster LA412 has the option of two different control board enclosures. Each control board enclosure contains the same LiftMaster control board. The control board on the LA412 and LA412 Dual has all of the necessary plugins for any accessories you wish to add to your gate opener. These can include exit wands, exit loops, edge devices, various safety devices, and locks. One down side of this control board is that it is very complex.
The larger control board enclosure, is made to hold a larger battery that you must provide. One downside of this box is that it does not hold a larger group size 24 deep cycle marine battery in this box. A battery of this size will be beneficial to you if live in an area that does not get a lot of sunlight for some periods of time. The standard control board enclosure comes complete with 2 batteries.
When you order from GateCrafters.com, you have the choice to choose the transmitters. Gate Crafters includes 2 transmitters of your choice, you can either receive LiftMaster transmitters or you can choose the Estate Swing transmitters. When you choose the Estate Swing transmitters you will receive an addition receiver. A couple positives of the Estate Swing transmitters is that we have successfully tested them up to ranges of 1400 feet, they are less expensive than the LiftMaster transmitters, and you will be able to use the Estate Swing wireless key pads as well.
Gate Crafters was started in 2002 with the goal of providing our customers with high quality gate openers. Our experts know gate opener inside and out and will be able to answer any questions you may have. We have technical support available 7 days a week from 9 am to 9 pm, eastern time. So please give us a call, send us an email, or use our live chat on our website, we are more welcome to answer any question you may have.”
"I bought my LiftMaster/Chamberlain LA412 in April 2013. I have waited a year to write about it because I wanted to be sure it was a good buy. I couldn't be happier! Installation took me just a couple hours because my gate and posts were already in place. I highly recommend reading the manual from front to back in a comfortable chair before starting. It helped to highlight instructions and pages that were specific to my gate. The gate works perfectly and quietly, every time. The solar charge has lasted me more than 40 openings and closings in a single day, and I'm sure it would go many more if I ever had the need. If you have sun, solar is the way to go!"
-Scott A. from Riverside, CA
"I was very impressed by the quality of the the gate construction and hinges. Equally, installation of the LiftMaster opener was clean and straightforward. After the posts were set, the entire installation took about a half day with the help of a friend. My wife loves it… no more getting in an out of the car! Thanks."
-Greg P. from Alpine, CA
"We bought this gate opener system (LiftMaster / Chamberlain LA412 Single Swing Solar Gate Opener with solar panel - with Standard Box) in September. It took me so long to install the system because I hurt my back at work. I had my friend help me install the system. I had to install the solar panel about 250 ft. away from the gate. I used 12 gauge stranded copper wire. I installed push buttons (door bell buttons) for visitors and emergency personal. The installation was easier than I thought it was going to be."
