This round push-button knob with trim ring is designed for spring-loaded “push-lock” mechanisms commonly used in boat and RV interiors. It allows you to latch and unlatch cabinets with a simple press – you push the knob to engage or release the locking mechanism. It’s made of durable ABS plastic with a chrome-plated finish, giving it the look of polished metal without risk of corrosion or heating up in the sun.
The knob is sized for a Ø25 mm cutout – a standard dimension for this type of latch. A spacer is included to ensure correct installation on panels of different thicknesses. Whether your cabinet door is a thin ~15 mm or a solid ~25 mm panel, the spacer helps position the knob properly so the lock operates smoothly. This makes the set versatile for various onboard furniture – from light cabinet doors to sturdier panels.
Installation is simple: place the bezel on the front of the hole, insert the knob through it, and secure it according to your latch mechanism’s instructions (usually by snapping or screwing it in from the back). The result is a clean, flush look – the knob sits nearly flat when locked and pops out slightly when pressed to the open position (depending on the mechanism).
This set is perfect if you’re replacing an old or broken push-button on your boat’s cabinet latch. It’s compatible with many models of spring locks (e.g., Osculati 38.182.40/50/51/54, etc.), so you can easily restore your cabinets’ functionality and give them a refreshed, modern appearance.
