Schweiss proudly introduces our newly designed and patented “Strap Latch”, offering simplicity, cleanliness and reliability every time you operate your bifold door.
Straps do the lifting and now straps do the latching! Schweiss did away with all the cables, chains, sprockets and pulleys; and it now has 90 percent less moving parts. This is a real game changer in the bifold door world! It doesn't get any better than an all-strap door.
Unlike other bifold door latch mechanisms, the new Schweiss design will firmly hold the door against your building in all positions; securing the door when open/partially open and will firmly lock the door when closed. it offers added protection from wind gusts while the door is in any position during operation. This innovative strap latch pulls your doorframe securely against your building making for a tight seal with each use.
Utilizing the door's existing drive line, it eliminates the need for an extra motor and additional parts such as additional cables or rod linkage.
This strap latch innovation simplifies the latching mechanism, reducing potential failure points, maintenance requirements, and operational complexity.
The “Strap Latch” boasts an exceptionally sleek appearance, seamlessly integrating with the same style strap that lifts your door, now doubling as a secure latch.
Straps secure the door while open!
Straps secure the door while closed!

Straps seal the door better!
Others offer an additional motor to power the latches that operates mechanical linkage rods connected to metal flippers to secure the door closed. This motor needs to be reliable and durable, as any malfunction can compromise the door's security or functionality.
Sometimes it latches, Other times it misses.
Motorized latching system involves numerous parts, increasing the potential for future issues.
Connect the motor to the latches, acting as the physical link that translates the motor's rotational or linear movement into the action needed to secure the door.
These are the components directly involved in engaging or disengaging the latch. They need to align precisely with the counter latch or strike plate to ensure a secure closure.
More components inherently mean more potential points of failure. The system could be sensitive to minor misalignments, wear, or external factors like wind or snow, as mentioned. Debris or obstruction by snow, for example, could prevent the door from latching properly.
Motorized latching system and mechanical linkage rods clutter up the interior of the bifold door frame, especially when the customers want windows in the bifold door frame. Also when it comes to line, the inside of the door frame makes it clumsy to sheet around the linkage rod for the latches.
You're dealing with 2 separate motors. To unlatch the door, the latch motor must engage first and go through the unlatching cycle. After the door unlatches, the drive line motor must start up and open the door. All this takes more time. It's a 2 step process that takes time, and time is money.
You're having to rely on its own separate motor and an extra electrical and moving parts of the linkage rods and flipper to secure the door against the building structure. Many things can be out of adjustment and at any time, that causes issues, not allowing your door pull back tight onto the building structure - too many variables!
It raises questions as to why some offer free motorized autolatches? It would make more sense to figure out a way to do away witht he extra motor and a less complicated latching system!
The door's existing drive line, that connects to the center cable drum.
A drum that winds and unwinds the latch cable off of the cable drum!
One cable that wraps around the Latch Drum. Another extra cable that is routed to each side of the door.
These are the components directly involved in engaging or disengaging the latch. They need to align precisely with the counter latch or strike plate to ensure a secure closure.
The drum cable tie's off to the both side latch cables. The drum cable tie's off to the center cable assembly that connects to both side latch cables.
Springs are typically used to keep tension on the Latch Cables.
Many moving parts to deal with. Lots of adjustments are needed to get your door latching properly.
Ongoing adjustments are needed to keep your door latching properly.
This type of mechanical latching system is initially more labor intense to install and costly to maintain over the years.
- Cables require more maintenance meaning more down time.
- Cables wrap next to each other and cause wear.
- Uneven cable wrapping causes problems.
- Slack cables cause problems.
- Cables tend to walk all over the lift drum and cause problems.
“I have done a lot of good research on bifold door latching systems and the only product, in my opinion, I can trust is your strap latching system. Less parts, tight seal, neater looking, more reliable!” - David
When using radio controls you must have the auto latching system. If not, provide lock safety switch to eliminate possible damage if door is opened in locked position.
All doors equipped with remote operators should have a warning system to alert persons in the immediate area that the door is moving.
Lets you open/stop/close your bifold door from any vehicle. Automatically unlatches the door so it can be opened or closed with the handheld remote. Two handheld remote controls and antennas are included with each door.
These let you open/stop/close your Bifold Door from any vehicle. Automatically unlatches the door so it can be opened or closed with the handheld remote. Two handheld remote controls and remote external antennas are included with each door. Automatic controlled doors require special attention to safety. Important Note: When using radio controls you must have auto latching system, if not provide lock safety switch to eliminate possible damage if the door is opened while in the locked position.
Warning System alerts remote operators. All doors equipped with remote operators should have a warning system to alert presons in the immediate area that the door is about to open or close.
