Claims20
A ladder top comprising:
- a surface;
- a front side flange extending down from the surface;
- a rear side flange extending down from the surface;
- a right side flange extending down from the surface having a right metal plate through which right fasteners extend into a right front rail and a right rear rail to attach the right front rail and the right rear rail to the right side flange;
- and
- a left side flange extending down from the surface having a left metal plate through which left fasteners extend into a left front rail and a left rear rail to attach the left front rail and the left rear rail to the left side flange.
A ladder comprising:
- a front assembly having a right front rail and a left front rail in parallel and spaced relation with the right front rail, front rungs attached to the right front rail and the left front rail and disposed between the right front rail and the left front rail;
- a rear assembly having a right rear rail and a left rear rail in parallel and space relation with the right rear rail, rear rungs attached to the right rear rail and the left rear rail and disposed between the right rear rail and the left rear rail;
- and
- a ladder top having a right side flange having a right metal plate through which right fasteners extend into the right front rail and the right rear rail to attach the right front rail and the right rear rail to the right side flange;
- a left side flange having a left metal plate through which left fasteners extend into the left front rail and the left rear rail to attach the left front rail and the left rear rail to the left side flange.
A ladder comprising:
- a front assembly having a right front rail and a left front rail in parallel and spaced relation with the right front rail, front rungs attached to the right front rail and the left front rail and disposed between the right front rail and the left front rail;
