A gutter ladder anchor formed from a metal plate, and comprising
- a flat base, having left, right, rear, and front ends;
- a fold at the front end of the base;
- one or more legs extending from the fold;
- a flange at the end of each leg, folded upwards;
- one or more holes located in each leg;
- a first pattern of spaced apart holes through the base for fixing the anchor to a batten or purlin, said first pattern extending from the left end to the right end;
- and
- one or more holes through the flange of each leg for fixing the anchor to a gutter.
The gutter ladder anchor of any of the preceding claims, wherein the base is T-shaped having a stem pointing backwards.
The gutter ladder anchor of any of the preceding claims, wherein an I-nut or I-bolt is mounted through the holes in the legs or flanges.
The gutter ladder anchor of any of the preceding claims, wherein a ladder locator bracket is fixed to the legs of the anchor by fasteners threaded through the holes in the legs and in the ladder locator bracket.
A one piece ridge anchor comprising,
- a rectangular metal plate folded into a U-shape, having an open end, a first leg and a second leg,
- an extension of the first leg at the open end having a hole for securing a worker;
- a first pattern of spaced apart holes through the first leg, said first pattern extending proximal to the open end and parallel to the open end;
- a second pattern of spaced apart holes through the first leg, said second pattern extending distal to the open end and parallel to the open end;
- and
- a third pattern of spaced apart holes through the second leg of the plate, said third pattern being aligned with the holes of the first pattern;
A one piece rafter anchor comprising
- a flat rectangular metal plate, having a top end;
- a flange extending substantially perpendicular from the flat plate at the top end, said flange having a hole for securing a worker and a plurality of holes for attaching ribbons for locating the rafter anchor under tiles;
- a plurality of spaced apart holes through the flat plate for fixing the plate to a rafter, said holes forming a pattern extending parallel to the top end.
A truss anchor comprising
- a flat rectangular metal plate, having a front end;
- a web upwardly extending from the front end;
- an extension extending from the top of the web away from the plate, the extension having a hole for securing a worker,
- a plurality of spaced apart holes through the plate for fixing the plate to a truss, said holes forming a pattern extending parallel to the front end.
