Straight edges
Single Straight Edge
The LAN-FLAT granite straight edges are made of South African black granite, in order to have the highest degree of precision, thermal stability and resistance to friction wear.
The straight edges are manufactured generally with one of the faces worked straight and flat (simple straight edges). With a high degree of flatness and straightness, the straight edges are supplied with a complete traceable report, valid for quality audits.

Parallel Straight Edges
The parallel straight edges present two of the faces worked flat and parallel to each other.
Likewise, the pairs of parallel edges are accompanied by a complete calibration report valid for quality audits.
