When I worked at an indoor wall we built an adjustable crack through the roof section (on the side). It was quite easy actually and involved lengths of timber (from memory about 2 x 8) thru bolted to the frame every 2 foot or so with a nut on the inside as a stopper, the idea being that you could slide the outside length of timber along the thru-bolts and tighten it at whatever width you wanted. Of course this also meant that if the crack was at wide hands size you could just grab the thru bolts! Worked really well at hands - fingers size and because it was straight sided with no grip paint on the inside you really had to use proper technique! It was a real challenge (starting off at 20 deg then going thru a roof and then up a vertical wall), even in hands crack size and I think only 1 bloke ever climbed it when it was set to finger crack size (Bob Cowan of course!).
