Quarter-Turns – simple latches through to keylocks requiring just a quarter-turn to operate
EMKA ex-stock quarter-turns are quick to fit and quick to operate latch locks which suit factory to office, computer room to laboratory where quarter-turns offer a simple and low-cost latching and locking system – some with spring clip fixing, others with back nut and an increasing focus on push/clip fit or other ultra-quick fit designs such as the EMKA 1022. So useful is the quarter turn concept that new sizes, styles and specialist designs are constantly being brought forward in materials such as hi-tech plastic, zinc die or stainless steel to suit new applications and more varied environments. Sizes vary from mini locks, generally for use on very small enclosures – even boxes – up to medium and large which may be employed on larger enclosures or cabinets. Where a single point closure is insufficient, then two quarter-turns are frequently installed.
Quarter-turns are the ubiquitous door closing workhorse of the enclosure world frequently offering IP65 degrees of sealing. The traditional quarter-turn layout is common in T handles and L handles which may or may not include a cylinder key lock for normal levels of security on medium to large enclosures/cabinets – also for access to machine protective cabins etc.
Often loosely categorised under quarter-turns are many compression latch/locks which are based on the same body pattern. Strictly they latch with a quarter-turn and then compress the gasket with an additional 90° turn., but offer a greatly enhanced level of sealing and vibration resistance eg in stainless steel for pressure washed hygiene areas.
Swinghandles, lifthandles and escutcheons
We have accumulated an extensive portfolio of modular design swinghandles, lifthandles and escutcheons for enclosures, cabinets, access panels and general industrial use to make life easier for specialist panel builders.
With over 30 designs in our 1100, 1200, 1300, 2000 and 3000 series we have all the options covered from IP40 to IP65 and in sizes from small (finger operated) up to large – full hand operation with substantial torque capability for closure of multi-point systems on large doors with significant gasket pull down.
There are a number of variants with electronic locks, remote locking and combination digit manual locks in-built to specific handles, which enable the specialist panel builder or installer to choose a suitable locking handle and internal cam + rods configuration.
EMKA solve the prominent door hinging dilemma
“How do I hinge my prominent cabinet door robustly and aesthetically?” is a question often faced by specialist enclosure/cabinet builders. Usually asked along with the caveat that it must be quick to fit and at reasonable cost. Well, typically, EMKA have a solution in our modular range of prominent door hinges to suit standard 20mm or 25mm returns, and even down to 6mm.
10 programs of hinge design cover requirements from concealed-with-removable hinge pin through simple lift-off butt hinges. Captive pins simplify door removal without the potential concern of losing the pin – while others make the installation process really quick by utilising the pivot pin as a concealed retaining device.
Prominent door hinges in this range are available in steel, zinc die, reinforced polyamide and in stainless steel which offer door openings of 115° to 180° with nested doors.

Profiles in EPDM, neoprene, PVC, black nitrate and natural rubber cover traditional expanded closed cell (self-adhesive) foam, through wiping blade and bubble or P type sections, with self-grip (clip-on), channel fixing and window type (with expansion insert), to more complex multi-functional and custom designs, perhaps with fillers or flocked weather strips and supported sections with internal or flange structural support.
This range includes EPDM, NBR, CR, PVC and silicone, as well as fire protection and hygiene specifications. Specialist considerations regarding shore hardness, tensile strength, recoil elasticity, abrasion resistance and climatic/chemical resistance can also be advised upon and allowed for in custom production.
