What is the self-fixing BILKA 210 mm bracket?

The BILKA 210 mm bracket is a long gutter hook, listed in the official catalog with a nominal length of 210 mm and cross-sections of 125 or 150 mm. It supports the gutter along the eaves and is fixed to a suitable base before laying the covering or according to the specific wooden detail. It is not a wall bracket for a downpipe and is not selected by diameter 90/100. The mounting position is determined by the geometry of the eaves.

What is the practical difference between the BILKA 210 mm and 160 mm brackets?

The difference is in the nominal length of the supporting arm: 210 mm versus 160 mm. The longer version provides a different area for positioning and fastening to the eaves but should not be interpreted as having higher load capacity without documentation. Both products have 125 and 150 mm variants. The correct choice is made after measuring the base, roof edge, and desired gutter position relative to the drainage line.

What colors and SKUs are available for the BILKA 210 mm gutter bracket?

Shopify contains 36 variants: 18 each for 125 and 150 mm cross-sections, with matte, glossy, or "Zinc" finishes. 125 mm / Matte / RAL 8017 is SKU LT-1299, and 150 mm / Zinc is LT-1333. For visible installation, the finish is usually matched to the gutter, but length and cross-section are checked first. The order must include the full name "210 mm" because the 160 mm hook is a separate product with different codes.

How many BILKA 210 mm brackets are needed for an 8 m straight gutter?

With a published spacing of 600-900 mm for an 8 m straight line, the guideline is approximately 10-15 hooks before accounting for corners, ends, and specific support points. The exact number depends on the chosen spacing and base layout. Support is added on both sides of each corner according to the instructions. The quantity is not calculated simply by dividing the total length if the line has breaks, funnels, or joints.

How is the slope formed with long BILKA 210 mm brackets?

The slope is set by measuring end points and marking each hook, not by approximate bending on site. The official catalog describes numbering the hooks and bending with a special tool along the drawn line. Depending on the document used, BILKA specifies 2-5 or 3-5 mm/m, so the instructions for the delivered system must be followed. Each hook must remain horizontal across the cross-section while the line slopes toward the downspout.

What is used to fasten the BILKA 210 mm gutter bracket?

The installation catalog provides for fastening through each factory hole with appropriate wood screws or nails depending on the base. The exact size and number are not universal data in the Shopify variant and should not be guessed. The wood must be solid and thick enough, without rotten sections. After fixing, the gutter grip, slope line, and absence of twisting that would alter the water edge position are checked.
