The Poro-Cav Lintel features a unique, patented ‘thermal break plate’ that enhances thermal performance. The inner leaf is supported through a standard Keystone Box lintel with factory fitted lateral restraint clips.
The outer leaf support comes from the uniquely designed outer lintel, which is easily clipped into position using the lateral restraint clip prefixed to the inner box lintel. This system provides resistance to rotation during loading on site.
Note:
External leaf specify PCO/K-90 (to suit 90-105mm cavity). For wider cavities and heavier loading conditions contact Keystone technical; department.
