Interlock Plank system - IPS

The Eltherington IPS is a pressed metal plank that is secretly fixed within the interlocking male and female joint. Available in a range of materials, finishes, face heights and lengths, this system can be fixed horizontally or vertically when installed on to our Hilti-Eurofox subframe.

The IPS is a top-down system which means the install starts at the top of the elevation, interlocking the top of one plank into the bottom of another.
