I have never used frame spacers and never liked them...limits to many options.
I imagine the proper beespace is the same in any equipment. could you get a tool for putting 9 in a ten frame body and either cut it down or grind of the ends to create the tool you need? then you would have the best of both worlds. lateral movement and deeper comb,.I like having lateral movement of the frames and would prefer just a spacing tool but was unable to find one for spacing 7 frames in an 8 frame body.
Because they are for honey spacing not brood spacing. So, if you have them for your brood nest then your combs will get more droney at the top and bottom bars. Drone spacing and honey spacing are the same. If you want your combs to stay worker, push them closer together...can't be done with spacers.Got them in all my boxes and love them. Why do you guys dislike them?
