What is the role of the BILKA adjustable self-fixing bracket?
The adjustable self-fixing bracket in Shopify is an adjustable gutter support for 125 and 150 mm sections. The image shows a hook with a mounting plate and an elongated hole, and the official BILKA catalog includes an adjustable hook in the same size groups. It supports the gutter and allows positioning relative to the front area, but it is not a bracket for the downpipe. The exact adjustment range is not published and must be confirmed by the factory detail.
Which BILKA adjustable bracket is chosen for a 125 or 150 mm gutter?
For a 125 mm gutter, the 125 mm variant is required, and for a 150 mm gutter, the 150 mm variant. These sizes follow the gutter part of the 125/90 and 150/100 systems and do not designate the downpipe. The hook must properly fit the profile without free movement or forcing. Before ordering, the gutter section, mounting location, and whether the adjustable plate is suitable for the actual front construction are checked.
What variants of the BILKA adjustable self-fixing bracket are available in LATIVA?
The product has 36 variants: 18 each for 125 and 150 mm, with matte, glossy, and "Zinc" finishes. 125 mm / Matte / RAL 8017 is SKU LT-1371, and 150 mm / Zinc is LT-1405. The same SKUs are also listed under the product "Front board bracket," indicating catalog overlap. Before offering, LATIVA must confirm which name and image correspond to the physical item under this code.
At what intervals are the BILKA adjustable brackets mounted along the gutter?
BILKA specifies 600-900 mm between gutter hooks and requires one support on each side of every internal or external corner. End positions are planned so the gutter is never unsupported at a cover or joint. The exact spacing depends on the base and load but must not exceed the published range. The adjustable mechanism does not compensate for rarely placed hooks or a weak front board.
What slope is set with the BILKA adjustable brackets?
The hooks are arranged along a pre-marked line toward the downspout, but official BILKA materials publish two close ranges: the current PDF catalog indicates 2-5 mm/m, and the installation webpage states 3-5 mm/m. Therefore, for a specific delivery, follow the system’s accompanying guide and the project’s drainage direction. The slope is not set visually only; the end points are measured and a string is stretched between them.
How is the fastener chosen for the BILKA adjustable self-fixing bracket?
The fastener is determined by the mounting plate holes, the front zone material, and the required anchoring depth. Shopify does not specify a universal screw or included kit, so it is incorrect to assume size based on the photo alone. The base must be solid, straight, and load-bearing; plaster or thermal insulation without proper anchors is insufficient. After fastening, the level, free clamping of the gutter, and stability of the adjusted position are checked.
