The Manfrotto 545B Pro Alu Video Tripod is a two stage, twin
leg, lightweight aluminum professional video tripod. Due to optimization
of the upper and lower collars, the tripod guarantees more torsion
rigidity and a payload of 55 lb plus improved shooting performance. The
die cast aluminum crown features a built-in 100 mm interface bowl, which
can be adapted to a 75mm if needed. The tripod is equipped with an
innovative mid-level spreader for improved tripod stability. It ships
with quick on-off rubber shoes for better grip on smooth floors.
