Profoto B10 adapter knob

These knobs are excellent idea and much better than the one came with . I love them and bought 2. Easy to tighten now and loosen. It wasn’t fun using the original ones as I kept tightening them and they would hurt my fingers.

If you've used the B10 strobes for any time you realize how difficult it can be to easily loosen and adjust the base knob. This product easily replaces the smooth rubber knob with a knurled handle that operates the tilt with little effort. I heartily endorse this product and this company for its innovations.


I love these new knobs, they have made my Profoto B10's and B10 Plus perfect - I was so frustrated with those round slippery knobs, so this was a fabtastic discovery!


These are fantastic!!! What a huge difference they made!

Great addition to B10

Like another reviewer mentioned be sure to check which knob you need before you order. I ended up needing the same version for my B10s and B10 Plus. PMG was very patient and helpful and now everything works great. It's unfortunate that a premium strobe needs additional parts but these are so much better. Great product and company.
