    Alignment Locks

    Precisely align and lock together your mold halves, so they stay in place during high-pressure injection molding. They're used as the final alignment between your mold halves, after leader pins and bushings (not included) guide your mold halves close together.

    Top locks install where the two halves of your mold meet, often called the parting line. Top locks require separately machined pockets on each half of your mold for installation. Because you’re machining both sides separately, you’ll need to take extra care to make sure the two pockets are aligned.

    Tapered round locks prevent sliding in all directions unlike top and side locks, which only prevent sliding in one direction. Install them where the two halves of the mold meet, often called the parting line. You’ll need to machine pockets in each half of your mold separately, so you’ll need to take extra care to make sure the two pockets are aligned. For a complete pair, you’ll need a male and female lock with matching ODs. The height does not need to match.

    Self-Aligning Remote-Release Rotary Latches with Safety Catch

    Image of Product. 1 Latch Point. Front orientation. Rotary Latches. Self-Aligning Remote-Release Rotary Latches with Safety Catch, 1 Latch Point.

    2 Latch Points

    1 Latch Point

    The slanted edges on these latches guide them into the strike bolt on your door, so the door will close even if it’s misaligned. They’re also known as dovetail latches and two-stage rotary latches. A safety catch stops your door from opening accidentally if it’s not pushed in all the way. You’ll know it’s not fully latched if the door rattles. Give the door an extra push to shut it completely. When closed, these latches grip the strike bolt on your door to hold it firmly shut. They require over 700 lbs. of pulling force to yank open, so they stay closed even in demanding applications. To open these latches remotely, you can connect them to a handle with a cable or rod (not included). This is especially useful when you want your latch hidden but your handle in an easy-to-reach spot.
    2 Latch Points—Latches with two latch points let you open the latch using two handles.
    FMVSS No. 206—FMVSS No. 206 rated latches have been designed and tested to meet rigorous Federal Motor Vehicle Safety Standard requirements.

    Remote-Release Rotary Latches with Cable and Handle

    For a complete latching system that you can open remotely, these latches come with a cable and handle. Mount your handle where it’s easy to reach and connect it to the latch with the cable. To close these latches, push them in, and they firmly grip the strike bolt on your door to hold it shut. Also known as single-stage rotary latches, they only have one latching position to keep them closed. Push them hard to make sure they don’t accidentally open.
