Abstract
Abstract The upper and lower ends of a hollow plastic corner post for a corner structure are each closed off with a device molded of a cuttable plastic whether or not the corner structure continues past the end of the post. The device includes a base having along the sides of one corner risers adapted to be received within the hollow plastic corner post. The other corner is marked with lines indicating distances from the edge near the ridge parallel to the lines. The distances from the outer edges of the corner post to interfering corner structure are measured, and material beyond the lines indicating these distances are cut from the base to form an indented corner. The trimmed device is then seated on the end of the corner post and fastened in position. The device for an end terminating flush with the surface of the structure may need no trimming.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A generally-square plastic device for closing off the end of a corner structure hollow plastic corner post partially embracing the corner structure, including a base and risers from only one corner of the base for engaging the sides of the interior of the corner post remote from the structure, and the base is formed of a readily cuttable plastic to facilitate trimming the base to precisely fit the corner structure and close off completely the corner post opening, and the risers are situated on the sides away from those where trimming will take place.
Claim 2
Dependent Claim
94 words
A generally-square plastic device for closing off the end of a corner structure hollow plastic corner post partially embracing the corner structure, including a base and risers from only one corner of the base for engaging the sides of the interior of the corner post remote from the structure, and the base is formed of a readily cuttable plastic to facilitate trimming the base to precisely fit the corner structure and close off completely the corner post opening, and the risers are situated on the sides away from those where trimming will take place.
Claim 3
Dependent Claim
38 words
A plastic device according to claim 1, wherein the risers are spaced from the outer edges of the base to define a lip on the base for engaging the edges of the sides of the hollow corner post.
Claim 4
Dependent Claim
21 words
A plastic device according to claim 1, wherein the risers are interconnected with a diagonal riser to form a strong construction.
Claim 5
Dependent Claim
31 words
A plastic device according to claim 1, having markings on the base about its corner opposite that having the risers for facilitating trimming the base to precisely fit the corner structure.
Claim 6
Dependent Claim
36 words
A plastic device according to claim 4, wherein the markings on the base about its corner opposite that having the risers are lines set off at regular intervals and perpendicular to the sides of the corner.
Claim 7
Dependent Claim
21 words
A plastic device according to claim 5, wherein the lines from one side interconnect with corresponding ones from the other side.
Claim 8
Independent Claim
97 words
A method of closing off an end opening of a hollow plastic corner post where the corner structure continues past the end of the corner post including measuring the distances from the corner structure to the outside sides of the corner post, cutting away a base having risers on one corner to engage the sides of the interior corner of the corner post remote from the corner structure on its opposite corner to distances proportional to the measurements, and inserting the risers in the corner post to close off the opening and precisely fit the corner structure.
Claim 9
Independent Claim
97 words
A method of closing off an end opening of a hollow plastic corner post where the corner structure continues past the end of the corner post including measuring the distances from the corner structure to the outside sides of the corner post, cutting away a base having risers on one corner to engage the sides of the interior corner of the corner post remote from the corner structure on its opposite corner to distances proportional to the measurements, and inserting the risers in the corner post to close off the opening and precisely fit the corner structure.
