Abstract
A scaffolding system includes a scaffolding assembly configured to support a worker above ground adjacent a structure and an end guardrail for integration with the scaffolding assembly. The scaffolding assembly includes a first vertical scaffold post and a second vertical scaffold post spaced apart from the first vertical scaffold post. The end guardrail is coupled with the first and second vertical scaffold posts and configured to block the user from passing through a space between the first vertical post and the second vertical post.

A scaffolding system comprising:
- a scaffolding assembly configured to support a worker above ground adjacent a structure, the scaffolding assembly includes a first vertical scaffold post, a second vertical scaffold post spaced apart from the first vertical scaffold post, a ledger extending between and interconnected to the first vertical scaffold post and the second vertical scaffold post, and a work platform supported on the ledger, the first vertical scaffold post having a first upright member, a first rosette, and a second rosette spaced apart vertically from the first rosette, and the second vertical scaffold post having a second upright member, a third rosette, and a fourth rosette spaced apart vertically from the third rosette, and
- an end guardrail configured to block the worker from passing through a space between the first vertical scaffold post and the second vertical scaffold post, the end guardrail including
- a rail assembly including a first vertical guardrail post, a second vertical guardrail post, and a first rail extending horizontally between and interconnecting the first vertical guardrail post and the second vertical guardrail post and adapted to block the worker from passing through the space, the first vertical guardrail post and the second vertical guardrail post being spaced apart to define an empty space between the first vertical guardrail post and the second vertical guardrail post,
- locating pin arms configured to locate the end guardrail on the scaffolding assembly during assembly of the scaffolding system, the locating pin arms including a first locating pin arm fixed with the first vertical guardrail post and a second locating pin arm fixed with the second vertical guardrail post, the first locating pin arm having a first extension member that extends away from the first vertical guardrail post and a first locating pin that extends into the first rosette of the first vertical scaffold post, and the second locating pin arm having a second extension member that extends away from the second vertical guardrail post and a second locating pin that extends into the third rosette of the second vertical scaffold post, and
- ledger head connectors configured to couple the end guardrail to the scaffolding assembly, the ledger head connectors including a first ledger head connector fixed with the first vertical guardrail post and a second ledger head connector fixed with the second vertical guardrail post, the first ledger head connector having a first support member that extends away from a first lower terminal end of the first vertical guardrail post and a first ledger head fixed with the first support member and removably coupled with the second rosette of the first vertical scaffold post, and the second ledger head connector having a second support member that extends away from a second lower terminal end of the second vertical guardrail post and a second ledger head coupled with the second support member and removably coupled with the fourth rosette of the second vertical scaffold post,
- wherein the first extension member of the first locating pin arm extends horizontally away from the first vertical guardrail post at a first angle relative to the first rail and the first locating pin extends generally vertically downwardly,
- wherein the first support member of the first ledger head connector extends downwardly and distally away from the first vertical guardrail post at a second angle relative to the first rail,
- wherein the first angle is different than the second angle.

An end guardrail adapted for use with a scaffolding system, the end guardrail comprising:
- a rail assembly including a first vertical guardrail post, a second vertical guardrail post spaced apart from the first vertical guardrail post to define an open space therebetween, and a first rail extending horizontally between and interconnecting the first vertical guardrail post and the second vertical guardrail post,
- locating pin arms including a first locating pin arm fixed with the first vertical guardrail post and a second locating pin arm fixed with the second vertical guardrail post, the first locating pin arm having a first extension member that extends away from the first vertical guardrail post and a first locating pin that extends downwardly from the first extension member, and the second locating pin arm having a second extension member that extends away from the second vertical guardrail post and a second locating pin that extends downwardly away from the second extension member, and
- ledger head connectors including a first ledger head connector fixed with the first vertical guardrail post and a second ledger head connector fixed with the second vertical guardrail post, the first ledger head connector having a first support member that extends downwardly and transversely away from a first terminal end of the first vertical guardrail post, a first ledger head fixed with the first support member, and a first wedge configured to extend into the first ledger head, and the second ledger head connector having a second support member that extends downwardly and transversely away from a second terminal end of the second vertical guardrail post, a second ledger head coupled with the second support member, and a second wedge configured to extend into the second ledger head,
- wherein the first extension member of the first locating pin arm extends horizontally away from the first vertical guardrail post at a first angle relative to the first rail and the first locating pin extends generally vertically downwardly,
- wherein the first support member of the first ledger head connector extends downwardly and distally away from the first vertical guardrail post at a second angle relative to the first rail,
- wherein the first angle is different than the second angle.
