Application

Designed for fitting into Twinfix multi-link and bar and sheet systems – consult manufacturer for details.

Description

In-line access hatch panel with 6 mm solid polycarbonate glazing. The product comprises three panels in total: two fixed panels (one at the top, one at the bottom, and one removable central panel).


Features and benefits:

  • Can be quickly and easily removed from below without the need for special equipment, enabling full 360° access (through canopy glazing to gutters, and other parts of the roof).
  • Creates a safer system of work for maintenance staff, with no need for scaffolding to be erected close to platform edges.
  • In-line design, which gives a sleek and unobtrusive finish to any roof.
  • Non-fragile.
  • Fast installation.
  • Suitable for use on heritage sites when used with Georgian glazing.
  • Long-lasting, low-maintenance, durable glazing is included, which won’t crack or break due to building or engine movement.
  • Green product, with glazing which may be recycled after use.
  • Maximum unsupported overhang: 150 mm.
  • Maximum unsupported span: 3200 mm (down the slope), 600 mm (panel width), and up to 1000 mm (removable hatch length).
