The Acorn Stair Lift: Acorn makes only straight stair lifts. Currently you can buy the Acorn Superglide stair lift. This home stair lift uses a modern rack and pinion drive system and is powered by DC 24 volt rechargeable batteries. The home stair lift also comes with two wireless remote controls with send/call features. You get safety sensors on both the footrest and carriage that will immediately stop the chair should any obstacle be encountered on the stairs or track. What sets Acorn apart is that they make a perch stair lift, which is ideal for those who have trouble bending the knees or for staircases that are narrower than normal.
Over the past several years, much has been done to address deck and stair safety issues, but we still have a long way to go. One glaring example of the failure in deck and stair safety protocol is the industry standard of permitting "hot dipped galvanized" anchors, screws, hangers and other hardware to be in direct contact with ACQ, pressure treated wood. The galvanic corrosion created between the high copper content of the wood and the galvanizing is so severe that the normal industry standard of G90 galvanizing will corrode in as little as 12 months and G185, such as Z-Max® can be gone in 24 months. The industry (including code officials) has adopted G185 as a fall back position with no engineering testing available to substantiate the validity or longevity of this adoption...this is a "knee jerk" reaction and is an accident waiting to happen. Without a barrier between the pressure treated wood and galvanized hardware, serious corrosion is inevitable.
