100% totally did this. Was a wood A-Frame ladder that went up 20'. Fucking fire alarm contractor 'forgot' to put the smoke head in the duct detector at the AMC in South Charlotte (not sure if it's still there) the fucking day before our final inspection. The unit was in the theater in the middle of the stadium seating. We had to break down chairs and build up materials to set the ladder. FUCK THAT , Me and a guy bigger than me put 2 of the legs on our upper thigh so the guy could go up. Took like 20 minutes.
HMM apparently wooden a frame ladders are no longer a thing, this is good they weighed 4 tons and were a bitch to set up. Was going to include a picture. This will have to do.
