The HE version is a cheaper version of the Studio Tek Cage maze system. Studio Tek has a special connector system that is extremely accurate. Several amusement parks are now switching to the Studio Tek wall system because of the ease of assembly. The HE version is a much smaller frame and no connection system. You must screw a bracket to the the frames and I think you even have to guess the right angle on them. The Studio Tek brackets are exact angles. We set a whole maze up without even striping off the maze on the floor. Just looked at the diagram, grabbed the correct angle bracket and moved to the next panel. Go to the other end and the maze was done!
Buy a cheap version of anything, suffer the consequences! Saw a knock off version of Pale Night's video asylum door in a haunt this season....boy you could tell the difference!!
Too many times you DO get what you pay for!!!
