Aluminium Hatch Locks (Large, 42mm)
Heavy-duty 42mm large ¼-turn hatch locks for RC boats requiring maximum hatch security. Quick-release spring-loaded design with CNC aluminium body.
Available in red or silver anodised finishes.
These 42mm large ¼-turn hatch locks are designed for larger RC boats and high-stress applications where hatch security is critical.
The quarter-turn locking mechanism provides fast, tool-free access, allowing hatches to be opened or secured in seconds—ideal for battery changes, electronics access, and maintenance between runs. The larger 42mm size offers increased holding strength, making these locks particularly suited to bigger hulls, petrol boats, and high-speed electric setups.
Each hatch lock is CNC-machined from aluminium for strength and precision, with a stainless steel spring maintaining consistent pressure to keep hatches firmly seated, even in rough water conditions. The anodised finish improves corrosion resistance while delivering a clean, professional appearance.
