Add the bolts and nuts you need for two universal focusers. If you’re adding our focusers to your own binocular project, this is the same high-quality stainless steel hardware we use in our own kits:

2x M4×12 bolt
2x M4 thin square nut
4x M4×25 bolt

⚠️ This product is available as an add-on to our printed focusers only. Your order will be cancelled if this item is purchased without focusers.
