Feature: Enclosures
The exact location of where the components belong depends on the type of cabinet being designed
With a through-hole angled arch, this is an ergonomic door handle design with aesthetic appeal. If the environment for the cabinet demands hygienic solutions, these stainless-steel cabinet handles are a great choice. Another option is a plastic pull handle with a female arch. Tese
arch cabinet handles are lightweight, which works well for indoor applications. For electrical junction boxes and other indoor electrical
cabinets, consider a recessed door handle, which is mounted flush to the door and is perfect for limited spaces. If looking for a quick and easy application, go for snap-in recessed handles, which work well for indoor telecom cabinets. A clamping lever is a handle that operates by lifting and rotating. The pushbutton allows for release and adjustment.
The adjustable clamping handle here lets the user position it for maximum leverage. For an industrial cabinet housed indoors, consider an L handle
cam latch, which offers ease of use, especially if space is limited. Turning the handle activates the mechanism; the cam rotating inside the handle opens the door. It’s not unusual for indoor cabinets to be placed in tight,
awkward spaces. In these instances, side hinges are a fantastic choice, providing 180˚ rotation. Te one to use depends on how heavy the cabinet doors are. If designing, say, a data centre server cabinet, then consider a lightweight but strong side hinge made of zinc alloy and stainless steel. For heavier doors where security is a consideration, such as an indoor electrical enclosure, use side hinges mounted with nuts. Tere are many different types of butt hinges. A butt hinge
comprises two parts that remain flush with each other when the cabinet door is closed. Te advantage of butt hinges over flush hinges is that they can support heavier doors. Rising butt hinges, also known as lift-off screw-mount
hinges, consist of two parts: one fixed to the frame and the other to the indoor cabinet door. When the door is opened, the leaf fixed to the door rises up. Rising butt door hinges work well when the door has to bypass a thick floor covering such as carpet or uneven floor. These are available as stainless steel rising butt hinges.
