The button wings are slightly taller than OEM, which improves engagement when operating the latch, especially with gloves on, a common complaint with the factory design. It does not change how the latch mounts or functions otherwise.
Yes. The bracket includes corrosion protection tape, which is pre-applied on the surface that contacts the aluminum window skin, creating a barrier against galvanic corrosion between the steel bracket and the aluminum airframe. This is something the OEM bracket does not have, often causing corrosion and cracks.
LH and RH refer to which side of the aircraft the window latch is on as viewed from inside the cabin facing forward. Check your existing latch's OEM part number stamp against the McFarlane unit, or ask us and we'll confirm from your tail number and model.
If only the handle rattles or won't hold the button, order the handle alone (MCS1483-1 or MCS1483-2). If the bracket is cracked or the latch won't seat into the striker plate, order MC1411202-201. If you're not sure, or both parts are original and worn, the 9114-LH or 9114-RH kit conveniently pairs the necessary components for replacement.
MCS1483-1 and MCS1483-2 are machined from stainless steel and heat treated to over 5x the strength of the original casting
MCS1483-1 is the right-hand handle assembly, replacing OEM S1483-1. MCS1483-2 is the left-hand handle assembly, replacing OEM S1483-2 and 0811725-40.
The factory handle is cast from a zinc-based pot metal with a smaller tensile strength. That's a soft material for a part that gets gripped, twisted, and slammed thousands of times, so cracking, wear, and a loose feel are common after awhile.
You can, but you're buying unknown history, no traceability, and the risk of hidden corrosion or fatigue damage in a casting you can't inspect from the outside. Used units will almost always have wear on them as well, and potentially may not latch your window closed properly.
