Triple-Bend Hinge for Industrial Cabinets

Those wholesale sourcing industrial cabinet hinges from Yitai Lock will find the Triple-Bend Hinge for Industrial Cabinets CL252 is one size only, at 38 × 37 mm — compact enough for smaller enclosure doors where a full-size hinge would look out of place. The triple-bend shape gives each leaf a stepped profile, which is what lets the hinge clear the door edge and frame lip without binding when the door swings. The Φ5 mm barrel runs through all three knuckles and keeps the pivot stable under regular door cycling.

Structure and Dimensions

The Triple-Bend Hinge for Industrial Cabinets measures 38 mm wide and 37 mm tall overall, with a knuckle span of 23 mm at the centre. The two leaves are asymmetric — the wider leaf is 14.5 mm and the narrower leaf is 11.5 mm — which means the hinge isn't reversible between door and frame without swapping sides. The barrel diameter is Φ5 mm, and the side profile shows a 15 mm total height with a 2 mm step at the bend, giving the leaf its offset shape.

Each leaf of the Triple-Bend Hinge for Industrial Cabinets has two mounting holes: Φ5.2 mm diameter with a Φ8×90° countersink, for four fixing points in total. The countersunk profile lets flat-head screws sit flush with the leaf surface, so there's no hardware standing proud of the hinge face after installation. Screw length should be selected based on the door panel and frame thickness at the mounting location.

Surface Treatment and Material

The Triple-Bend Hinge for Industrial Cabinets is available in two material options. The carbon steel version carries a galvanized finish that provides corrosion protection for standard indoor enclosure environments — distribution boards, control panels, and equipment cabinets in dry or climate-controlled spaces. It's the more common choice for general industrial cabinet applications where cost and corrosion requirements are both moderate.

The 304 stainless steel Triple-Bend Hinge for Industrial Cabinets goes through vibratory polishing, which gives a consistent matte surface by tumbling the parts to remove burrs and sharp edges. This isn't a brushed or mirror finish — the result is a low-sheen, uniform appearance suited to industrial use. The stainless version is the right pick for enclosures in humid environments, outdoor installations, or anywhere the galvanized carbon steel finish wouldn't hold up over time.

Application Scenarios

The Triple-Bend Hinge for Industrial Cabinets is a practical fit for electrical distribution panel doors, switchgear enclosures, and industrial equipment cabinet doors where a compact, screw-mounted hinge with a 90° opening angle is what's needed. The small footprint works well on lighter cabinet doors and enclosures where a large hinge would be out of proportion with the door size.

The screw-only installation on the Triple-Bend Hinge for Industrial Cabinets also makes it suitable for cabinet manufacturers who don't weld hinges during fabrication — the four countersunk fixing points go directly into the door panel and frame without any additional preparation. The 90° opening angle is enough for most panel access requirements, and the flush screw seating keeps the door face clean once the hinge is fitted.

FAQ

Q1: What are the dimensions of the CL252 hinge?

The CL252 is 38 mm wide and 37 mm tall overall, with a knuckle span of 23 mm. The two leaves are asymmetric — 14.5 mm on one side and 11.5 mm on the other. The barrel diameter is Φ5 mm.

Q2: How is the CL252 installed?

Installation is by screw mounting only — no welding. Each leaf has two Φ5.2 mm countersunk holes (Φ8×90°), giving four fixing points in total. Flat-head screws sit flush with the leaf surface after installation.

Q3: What materials are available?

The CL252 comes in galvanized carbon steel and 304 stainless steel with a vibratory polish finish. Carbon steel suits indoor, dry environments; stainless steel is the better choice for humid or outdoor enclosure applications.

Q4: What is vibratory polishing?

Vibratory polishing is a tumbling process that removes burrs and sharp edges from the part surface, leaving a consistent low-sheen matte finish. It is not a brushed or mirror finish. On the CL252 stainless steel version, it gives a uniform industrial appearance without reflective or directional surface marks.

Q5: Are the two leaves interchangeable between door and frame?

No — the leaves are asymmetric (14.5 mm and 11.5 mm), so the wider and narrower sides are fixed. Make sure to orient the hinge with the correct leaf against the door panel and frame before drilling or fixing.

Q6: What cabinet types is the CL252 suitable for?

The CL252 industrial cabinet hinge is used on electrical distribution panel doors, switchgear enclosures, control cabinet doors, and general industrial equipment cabinets — particularly where a compact, screw-mounted hinge is preferred and a 90° opening angle is sufficient.
