Modular perimeter fencing system

A fencing system comprising:

• a first post configured to be anchored to the ground and comprising a first passageway through the first post;
• a second post configured to be anchored to the ground at a distance from the first post and comprising a second passageway through the second post;
• a rail member that, with the first post anchored to the ground and the second post anchored to the ground at the distance from the first post, is received within the first passageway of the first post and the second passageway of the second post, a length of the rail member extending between the first post and the second post;
• wherein the rail member comprises a first side and a second side opposite the first side, wherein the rail member comprises (i) a lengthwise opening along the first side of the rail member and (ii) a plurality of holes at the second side of the rail member, and wherein the plurality of holes are opposite the lengthwise opening;
• wherein, with the rail member received within the first passageway of the first post and the second passageway of the second post and the length of the rail member extending between the first post and the second post, a fence panel is attached at the length of the rail member between the first post and the second post and at the second side of the rail member;
• and
• wherein the fence panel is attached at the second side of the rail member via a plurality of fasteners that are disposed through respective portions of the fence panel and respective holes of the plurality of holes, and wherein the plurality of fasteners are disposed partially within the rail member.

• a rail member that, with the post anchored to the ground, is received within the passageway of the post, a length of the rail member extending from the post;
• wherein the rail member comprises a substantially C-shaped rail member having an upper portion, a lower portion, and a side joining the upper portion and the lower portion, the upper portion and the lower portion extending from the side and being spaced from one another so as to define a lengthwise opening along the length of the rail member, and wherein the side of the rail member comprises a plurality of holes therethrough;
• wherein, with the rail member received within the passageway of the post and the length of the rail member extending from the post, a fence panel is attached at the length of the rail member at the side of the rail member;
• and
• wherein the fence panel is attached at the side of the rail member via a plurality of fasteners disposed through respective portions of the fence panel and through respective holes of the plurality of holes through the side of the rail member.
