opalescent – glass poster trap frame with alu fixing

The Opalescent signage system delivers a stylish and practical, yet discreet touch to interior and external environments.

This versatile, simple fixing was designed by Gerard Plenacoste and is fast becoming the system of choice for specifiers looking for a more elegant signage solution that also meets DDA and accessibly regulations.

Opalescent DTP insert signs comprise an elegant aluminium profile with a range of finishes including a natural anodised micro sandblasted, brushed and mirror polished finish.

Combined with tactile and Braille, Opalescent is the perfect media for DDA compliant signs and can be used as wall-mounted, projecting or free-standing signage.

Two material widths of 5.5mm and 10.5mm thick can be accommodated using glass (V-Verre) or silica acrylic (P-PMMA) and backed with 1.5mm satin anodised aluminium.

The Opalescent signage system is only available to purchase in the UK from Signbox.
