Fuminas has in its portfolio the TPF02 inspection covers for fiber optic and telephonic pass boxes. They are bi-articulated and have a locking system by bolt or lock. Produced with nodular iron FE 50007 (Class 125), they meet NBR 10160. Just like the category models, they are non-slip and have a locking system at 110 ° (not to "fly" on the operator).
