SPEP Quality Defeater Handles

Our products are designed and manufactured to a high degree to maximize production and durability, giving our customers a high-quality product they can depend on. Defeater handles are a great example of this, giving a high-quality solution for security, safety, and durability for a wide range of enclosures.

Secure, Safe Defeater Handles

Defeater handles are a type of handle mechanism that requires a two-handed operation for both safety and security. This also allows for the additional safety measure of automatic locking. Our patented padlockable defeater handle is available as key locking, tool access, or non-locking to suit your needs, depending on the level of security you require. The spring loaded tab accepts up to a 3/8” size padlock.

Defeater handles are highly recommended anytime additional restriction is needed, as the mechanism type itself offers added protection. SPEP defeater handles are intended for NEMA 4x enclosure requirements, with a sealing gasket built into the escutcheon. These are recommended for both indoor or outdoor use in a variety of industries.

Our defeater handles provide a variety of mounting options too, using a provided body nut, and multiple holes. These bi-directional handles are similar to quarter turn latches and may rotate 90 degrees both clockwise or counterclockwise with the help of its removable stop washer.

We also manufacture a range of defeater handle cams to accompany our defeater handles as a separate component. This added flexibility in application gives a variety of different combinations uses so you can find the set that will work best for your NEMA enclosure or other projects. While we host many different types of defeater handles and defeater handle cams, there can always be times where the exact component isn’t available off the shelf. If you can’t find exactly what you’re looking for in our catalog of defeater handles, contact our team who can develop a custom defeater handle and cam system exactly for your project.
