Customer ratings for Alloy Module Holder for 16mm Modules

Used for 16mm green laser modules on continuous operation. These are tight on the modules I have but inserting a screwdriver in the slot opens them up for first mounting. They are not the best heatsink in the world as they have no fins but definitely help if clamped at the level of the diode base. This is usually halfway along the module if in doubt feel for where the heat is coming from! Now moving 515nm which won't get as hot so these are great.
