Lockable Electrical Boxes

Lockable electrical enclosures and lockable junction boxes are NEMA and IP-rated for weatherproof outdoor protection. Designed to keep your components secure in any environment, our locking waterproof boxes protect equipment from unwanted tampering. Lockable outdoor boxes are available in corrosion-resistant plastic and metal varieties. Plastic lockable electrical enclosures provide added security while staying lightweight and durable. Lockable metal boxes, available in steel and stainless steel, are a heavy-duty solution providing natural RFI/EMI shielding. Our locking electrical boxes are available with optional accessories like internal panels, pole mount bracket kits, or DIN rail electrical enclosure kits.

Lockable Electrical Boxes: Key Features and Uses

A locking electrical enclosure is a must-have for any application where equipment security and access control are high priorities. That could include using an outdoor outlet box to guard outdoor receptacles against unauthorized use, preventing unauthorized access to critical equipment like a security control panel, and numerous other applications. Read our blog post on lockable NEMA enclosures to learn more about applications that benefit from lockable enclosures.

These enclosures are available in various configurations. Some offer built-in keyed locks directly integrated into the enclosure cover. Other enclosure models include a padlock hasp, typically attached to the enclosure’s latch or cover seam, so the end user can supply their own lock.

Whichever security mechanism they use, lockable enclosures must be made from durable materials — such as stainless steel or fiberglass-reinforced polycarbonate — to ensure they can’t be defeated by brute force. Additionally, in many applications, weatherproofing features such as waterproof and dustproof gaskets are critical for protecting equipment. For these reasons, it’s crucial to choose high-quality lockable enclosures with the specific performance features you’re looking for.
