Anyone know how to mount barn doors on a par 56 can? I see things like this for sale but Im not clear as to how they go on to the can.
Conventional barndoors always attach by way of the gel frame slot. You should be able to fit barndoors and a gel frame in the same slot but if you can't then you can always use a fibre-board gel frame instead of a metal one since they are much thinner. The one thing to keep in mind is that the safety cable built into some barndoors might not reach the yoke on a PAR can since it is longer than a same-aperture fresnel but you can always use a second safety if need be.
The better barndoors have a slot for a gelframe, so you don't need to double-up on the instrument's accessory slot. Helps prolong the life of the gel, too.
I've noticed that the yoke on parcans often doesn't tighten firmly enough to stay in place with the additional weight of barndoors on the front.
