Adjustable Stainless Steel Ball Catch

For those wholesale sourcing cabinet door catches from Yitai Lock, the Adjustable Stainless Steel Ball Catch MP103 series covers a useful size range in a consistent design — from the compact 43mm body for lighter cabinet doors up to the MP103-1 with a striker plate included for heavier-duty applications.

Model Options and Dimensions

The Adjustable Stainless Steel Ball Catch is available in four sizes with the following key dimensions:

· 43mm model: Overall length 43mm, body width 8mm, height 13.6mm, roller height 10.3mm, 4×M3 screw holes, inner ball span 16mm, base width 25mm

· 50mm model: Overall length 50mm, body width 10mm, height 15mm, roller height 12mm, 4×M4 screw holes, inner ball span 20mm, base width 30mm

· 70mm model: Overall length 70.5mm, body width 13mm, height 22.5mm, roller height 17mm, 4×M4 screw holes, inner ball span 30mm, base width 43mm

· MP103-1: Body plate 65 × 29mm with 4×Φ4.6mm holes and 50mm inner span; striker plate 61 × 26.7mm with 2×Φ6.2mm holes and 45mm inner span; spring depth 28mm, total assembled depth 41mm

Finish Options

The Adjustable Stainless Steel Ball Catch is offered in three surface finishes depending on the model:

· Satin finish (grinding finish): Available on the 43mm, 50mm, and MP103-1 models. A fine ground surface that gives a consistent, low-sheen matte appearance — suits most standard cabinet and wardrobe applications

· Brushed finish: Available on the 70mm model. A directional brushed surface with a slightly more refined appearance than satin — commonly specified for kitchen cabinetry, furniture, or interior joinery

· Mirror finish: Available on the 70mm model. A fully polished, reflective surface for installations where the hardware finish needs to match polished stainless steel fittings or decorative cabinet hardware

All finishes are on 304 stainless steel, so corrosion resistance is the same across the catch range regardless of which surface finish is selected.

Installation and Adjustment

The catch is screw-mounted on all models. The body mounts to the cabinet frame or door jamb, and the door face makes contact with the dual-ball track when the door closes.

The ball tension on the Adjustable Stainless Steel Ball Catch is adjustable, which means the resistance the door feels when opening and closing can be tuned after installation. This is a useful feature when the catch is used on doors of varying weights, or when the initial tension feels too stiff or too loose once the door is hung. No special tools are required for adjustment beyond a standard screwdriver.

Application Scenarios

The Adjustable Stainless Steel Ball Catch is used across a wide range of door types:

· Cabinet doors — kitchen cabinets, bathroom vanities, utility cabinets, and built-in joinery where a click-shut action is preferred over a magnetic catch

· Wardrobe doors — hinged wardrobe panels where a ball catch gives a clean, hardware-free appearance on the door face

· Cupboard and pantry doors — lighter doors where the 43mm or 50mm model provides the right amount of holding force without being too stiff to open

· Furniture and display cases — the mirror and brushed finish options on the 70mm model suit furniture or display cabinet applications where the catch finish needs to match other visible hardware

· Heavier cabinet and enclosure doors — the MP103-1 with striker plate is the right pick for doors that are too heavy for the standard dual-ball models to hold reliably

FAQ

Q1: What sizes are available in the MP103 ball catch range?

The range covers four models: 43mm, 50mm, 70mm, and MP103-1. All are 304 stainless steel and screw-mounted. Size selection depends on door weight, panel size, and required catch force.

Q2: What makes the MP103-1 different from the other models?

The MP103-1 is the largest model in the range and includes a separate striker plate that mounts to the door face. This gives a defined contact point for the ball mechanism, making it better suited to heavier or thicker doors where the standard dual-ball track alone may not provide enough holding force.

Q3: Is the ball tension adjustable on all models?

Yes — ball tension is adjustable on all models in the range. The catch force can be tuned after installation using a standard screwdriver, which is useful when the initial tension needs to be increased or reduced to suit the door weight or user preference.

Q4: How is the ball catch installed?

All models are screw-mounted. The body is fixed to the cabinet frame or door jamb, and the door closes against the dual-ball track. The MP103-1 additionally requires the striker plate to be mounted on the door face. No specialist tools or adhesives are needed.

Q5: Is the ball catch suitable for outdoor use?

304 stainless steel handles indoor environments and lightly sheltered outdoor use well. For fully exposed outdoor installations in coastal or highly corrosive environments, it's worth confirming that the finish and environment are a good match before specifying.

Q6: Which model should I choose for heavy cabinet doors?

The MP103-1 is the right pick for heavier doors — the larger body, stronger spring, and included striker plate give it more holding force than the 43mm, 50mm, or 70mm models. For standard-weight cabinet and wardrobe doors, the 50mm or 70mm model covers most applications.
