ScorpionÂ® TMA Truck Mounted Attenuator. The Scorpion line of Impact Attenuators, by TrafFix Devices, Inc., are truly different by design. The Scorpion TMA consists of strut and cartridge sections that are linked together on a support frame.
Any questions you can e mail me through my avatar. The metal used between tile and carpet is called a Z bar. It is a hidden metal that is put under the wood tack strip and the carpet is tucked in to it. The result is a hidden metal and the carpet looks as if it were tucked tight to the carpet. Transition strip.
You can use 1/2â³ plywood over 1/2â³ plywood for the subfloor (I would stagger the joints and glue the two layers together with construction adhesive), but you still need a layer of either cement backer board or underlayment membrane under it so the tile will adhere properly.
