Height-adjustable extension with bituminous collar, for balcony drain series HL3100T and HL5100T HL8500H

Extension for balcony and terrace drains

This element is an indispensable solution when building or modernizing drainage systems for terraces and flat roofs. The extension, made of high-quality polypropylene, allows for height adjustment of the drain and ensures a tight connection with the next bituminous sealing layer. This is particularly important in complex structures where precise alignment of the drainage elements to the existing insulation layer is required.

The HL8500H extension is dedicated to working with balcony drains from the HL3100T and HL5100T series, as well as with extensions HL3400, HL8500 and the HL150 drainage ring. This makes it possible to create a comprehensive and reliable water drainage system. Height adjustment is done by simply cutting the extension, allowing it to be adapted to specific mounting needs - the total height of the element is 226mm.

• Versatility: Compatible with popular balcony drain series HL3100T and HL5100T and other Hutterer & Lechner accessories.
• Height adjustment: Allows precise adjustment to the bituminous sealing layer by easily cutting the extension.
• Tightness: Ensures a tight connection with the sealing layer thanks to the use of a bituminous collar.
• Durability: Made of durable polypropylene, resistant to weathering and mechanical factors.
• Flexibility: Together with other accessories, it allows for the creation of drainage solutions for flat roofs/terraces with very diverse layer arrangements.

The HL8500H extension is not only a technical element, but above all a guarantee of proper drainage system operation and protection against the effects of dampness on the building structure. Its solid construction and thoughtful design translate into long-term reliability and minimal operating costs. Installation is simple and intuitive, which will be appreciated by both professional installers and people performing renovation or construction work independently.
