BENRO C-298M8 Carbon Flexpod Center column converts into a lateral arm, which is especially advantageous for nature and on-location industrial shooters. Dust and water-resistant leg lock design prevents dust or moisture from entering the interior of the leg twist-locks. Three leg-angle positions let you work on uneven terrain or in awkward shooting situations. Removable rubber and stainless steel spike feet provide a secure grip, both indoors and outdoors. The retractable spring-loaded center column hook can be used to add stability with a sand bag or equipment bag
