<p>An adjustable rainwater gutter bracket consists of a bracket arm (1) with horizontal teeth (17) at its rear, a mounting block (3) with horizontal teeth (37) at its front, and a locking slide (5) housed in the mounting block. Lugs (21) on the bracket arm can enter a channel in the mounting block to retain the bracket arm loosely while allowing the teeth to be inter-engaged at different relative heights. The locking slide can lock a hook (57) provided on the bracket arm, to hold the bracket arm against the mounting block with the teeth firmly inter-engaged. This enables the height of the gutter to be easily adjusted. The mounting block is installed first, the bracket arm is fitted to it subsequently. A gutter seal strip (69) may have an integral resilient pad (91) at its end, to be trapped between the gutter edge and a rigid retaining clip (77) of a gutter fitting, to retain the gutter reliably without requiring accurate moulding of the gutter fitting. The seal strip may have a non-uniform external cross-section with a rib (75) engageable in a recess provided in the fitting, to retain the seal strip without requiring an end lip on the fitting. The seal strip may incorporate stiffer edge regions (83, 85).</p> |
