Heavy and thick door DT83 lever breakage replacement repair

"The lever broke, so I'd like to request a replacement quote."

The place is a prime location in Tokyo.A certain foreign car dealer showroom.At the place guided behind, there is a steel door for the carry-in entrance, which is likely to be 3 meters high.

The lever is broken from the shaft.It is damaged so that it can be torn at the base of the room.When I checked it, it was U9.LA, but what surprised me was the thickness of the door. There are 83 mm.

I don't know the weight.I was surprised that this lever supported the door.

I disassembled it and examined its structure, but I couldn't admire the mounting method.It was not an installation method that understood the place where concentration was applied.

I knew that an approval was needed, so I said, "It's a custom-made product, so I'll submit it at a later date."The result was sent off, but I was allowed to see a good one.
