Manfrotto 183 Aluminum Projector Platform

I bought this Manfrotto 183 Aluminum Projector Platform to be used with my Optoma HD142x projector. This thing is really SOLID. I'm sure it could get run over by a truck and still be perfect for use. Please keep in mind that the solid aluminum does pack a little weight and you'd be fine if you're okay with that. I conveniently have the Manfrotto 190XPROB legs with the 804RC2 head to be used with this platform. It's perfect. 3-way pan/tilt allows me to adjust the position of the projector conveniently to align with the wall with minimal use of keystone adjustments via projector. I think what would make this setup superb is if there was someway to make a cage for the projector in the odd event that it falls, the projector is safely affixed in to avoid falling and hitting the ground hard. On a side note, I find that the weight of the platform does keep the legs anchored into the ground and feels safer. To use it, all you have to do is get the tripod head's mounting plate and screw it in the bottom of the platform with its provided thread and you can mount it on the tripod like a camera does.
