Frequently Asked Questions
What is a paddle latch?▼
A paddle latch is a flush-mount latching mechanism where a flat, rectangular paddle handle sits recessed in a pocket cut into the door panel. When closed, nothing protrudes from the surface. To operate, pull the paddle out and rotate it to release or secure the door. Standard on truck toolboxes, industrial enclosures, and electrical panels.
What is the difference between a flush paddle latch and a pop-out paddle latch?▼
A flush paddle sits perfectly flat when closed. A pop-out paddle is spring-loaded and pops up above the panel when unlocked, making it easier to grip. Flush paddles offer the lowest profile and best sealing; pop-out paddles are preferred for frequent access. Both achieve IP65+ with proper gasket design.
Can paddle latches achieve NEMA 4X or IP66 ratings?▼
Yes. With 316 stainless steel construction and EPDM or silicone gaskets providing 20–30% compression, paddle latches meet NEMA 4X (IP66 + corrosion resistance). Read our NEMA ratings and installation guide for detailed specifications.
Can paddle latches be locked?▼
Yes. Locking paddle latches integrate a key cylinder requiring a key to open. Available keyed-alike, keyed-different, and master-keyed. We also offer combination (keyless) paddle latches for fleet operations where keys are impractical.
What cutout size do I need for a paddle latch?▼
Standard cutouts: 92×42 mm (standard), 120×92 mm (large), 64×32 mm (compact). Rectangular with rounded corners (R3 or R5). We provide DXF cutout templates for every model. Even 1 mm deviation can compromise the gasket seal.
What is the MOQ for custom paddle latches?▼
MOQ is 500 pcs for catalogue models, 2,000 pcs for custom designs. CNC prototypes in 7–10 days. Die-cast tooling 30–45 days. Mold subsidy available based on annual volume commitment.
