Compression Latches — IP65/IP67 Flush-Mount Plane Locks

Flush-mounted plane locks for electrical distribution cabinets, control panels, and HVAC equipment enclosures.

33 models available

Compression latches (also called plane locks or flush locks) use a quarter-turn mechanism that converts rotational motion into axial compression, pulling the enclosure door tight against its gasket. This creates dust-tight and water-resistant seals from IP54 up to IP67. Selecting the right compression latch requires matching the latch travel, cam geometry, and material grade to your enclosure's sealing requirements, environmental exposure, and access control needs. Below is a selection guide based on 35 years of manufacturing experience across telecom, EV charging, HVAC, and data center enclosures.

Compression Latch Selection Guide

Type	Mechanism	IP Rating	Best Applications
Quarter-Turn Fixed Cam	90-degree rotation, fixed cam stroke (2-4 mm)	IP54-IP65	Indoor electrical panels, HVAC control boxes, vending machines
Adjustable Compression	Threaded cam body adjusts compression 2-8 mm	IP65-IP67	Outdoor telecom cabinets, EV charging stations, food-processing enclosures
Push-to-Close (Slam Latch)	Spring-loaded auto-latching on door close	IP54-IP65	High-frequency access panels, server rack side panels, quick-release covers
Key-Locking Compression	Quarter-turn + cylinder lock, keyed-alike/different/master	IP65-IP67	Multi-cabinet installations: data centers, telecom sites, EV charging networks
Lift-and-Turn	Recessed handle lifts before turning to prevent accidental release	IP65	Vibration-prone environments: mobile generators, vehicle-mounted enclosures

Key Selection Factors

Gasket Compression Range

The latch cam travel must compress your gasket 20-30% of its uncompressed height. Under-compression causes leaks; over-compression accelerates gasket fatigue. Adjustable-compression models let you dial in the exact stroke after installation, making them the safest choice when gasket thickness varies across your enclosure production run.

IP Rating vs. Material Grade

Achieving IP65 requires proper gasket selection plus a structurally rigid latch body that won't flex under compression force. Zinc alloy (Zamak 5) handles most indoor and sheltered outdoor applications. For marine, coastal, food-grade (FDA wash-down), or chemical environments requiring IP66/IP67, specify 304 or 316 stainless steel bodies. Our 316 SS models pass 1,500+ hours of salt spray testing per ASTM B117.

Access Control Options

Standard tool-operated slots suit utility enclosures where technician access is controlled by policy. Key-locking models add physical security for high-value equipment. For multi-site deployments (telecom cell sites, EV charging networks), keyed-alike configurations let technicians carry a single master key. We maintain key databases across production batches to ensure consistency.

Panel Cutout Compatibility

Most compression latches install through a standard D-shaped or round cutout. When replacing existing hardware, measure the existing cutout diameter and door thickness. Our engineering team provides drop-in replacement recommendations — send us your current latch model number or a photo of the cutout for a match within 24 hours.
