36:T543,

Comfortably holds two modular helmets
Features Monokey, which allows for a single lock to open and release the plate with the same key
Compatible with all Monokey plates, apart from those with the stop light kit connection
Case is released from the plate by turning an external knob that is equipped with a cable system and placed directly under the Security Lock (not necessary to turn the knob to attach the cases)
Two handles placed on the back of the top case, which are also integrated with the strong hinges on the lid, allowing the latter to open more fully without the need for classic retention cables: once opened, the lid is held in position in order to make packing/unpacking easier
Four belt-strap loops integrated into the structure of the lid, set into the contoured lid to give an elegant shape to the whole case
Set up to allow the attachment of a backrest (available for purchase as an optional) using screws, without the need to pierce or attach any component with adhesive
Rivets fitted with gaskets and sealed using silicone, to ensure water tightness even under the worst riding conditions
A series of grips built into the interior, integrated into the supporting structure, allowing loads to be attached to both the lid and bottom of the case
