Ironmongery/ Accessories:

All fittings are corrosion-free and are concealed within the profiles.

Panels are latched and unlatched by means of internal, flat handles with 180° rotation; lockable handles are optional. Handles are available in four RAL colours as standard – other finishes available on request. Aluminium locking bars, with minimum 24 mm travel, act on the top and bottom track; bar ends are fitted with polyamide caps to prevent metal to metal contact.

Standard ironmongery for entry/ exit door: Handle inside and outside; three point locking handle and cylinder available as an option.

Fasteners are width-adjustable for optimum adjustment of the folding system. Secure hinges are fitted to hinder break-ins. Hinges available in one RAL and two EURAS eloxal colours.
