They stop snow drifts from the canopy.
They attach to the roof depending on the type of snowplow:
The tile snow clamp is attached to the tile, the shingle snow clings to the nails, and the trapezoidal sheet snow clamp is secured with screws, eraser and washer.
The optimum distance between the snowblower is 1 meter and it fits in 3 rows. They are also made on a fully automated production line that provides superior and uniform quality for each individual piece.
