The Modular Helmet Ratchet Assembly is a detachable and replaceable adjustment mechanism designed for both LAND Aeropro, Climbpro, Multipro safety helmets. Featuring a quick-release design, smooth indexed adjustment, secure locking performance, and simple installation, it provides a convenient and cost-effective solution for replacing worn or damaged components without requiring replacement of the entire helmet assembly.
Beyond its primary head-lock adjustment function, this modular system enables interchangeability between the ratchet assemblies used in our AEROPRO and CLIMBPRO helmet models. If a helmet feels too loose due to a smaller head circumference, there is no need to replace the entire helmet. Simply install a smaller head-lock adjuster (sold separately) to achieve a more secure and comfortable fit.
This modular design also reduces maintenance costs. If the head-lock mechanism becomes damaged or worn, only the ratchet assembly needs to be replaced, eliminating the expense of purchasing a new helmet.
For example, those who purchased an AEROPRO helmet but require a smaller fit can replace the standard head-lock system with the CLIMBPRO Small-Size Head-Lock System (Part #_LAND-RACHET-CLIMBP-SM_________). This flexible design provides a simple, economical, and customizable fitting solution.
The ratchet assembly incorporates a precision-engineered rotating adjustment mechanism and dual snap-in mounting interfaces. The system provides smooth, incremental adjustment while maintaining secure locking performance throughout its operating range.
Its modular architecture allows both the ratchet assembly and head-lock adjuster to be independently removed and replaced. This design extends product lifespan, simplifies maintenance, and enables riders to customize helmet fit according to individual head shape and size requirements.

MODULAR DESIGN. LOWER OWNERSHIP COST.
Replace only the ratchet assembly—not the entire helmet. The detachable, tool-free design makes maintenance fast, simple, and cost-effective, extending helmet service life while reducing replacement costs for crews and fleet managers.


CUSTOMIZE YOUR FIT. UPGRADE YOUR COMFORT.
The interchangeable head-lock system allows you to swap ratchet assemblies between LAND AeroPro, ClimbPro, and MultiPro helmets to achieve a more precise fit. Whether replacing worn components or selecting a different head-lock size, the modular system delivers personalized comfort without replacing the helmet.
