Best Tripod With Bubble Levelings

RV T Levels (2-pack) plus 4 Free Screws; Use to Cross Check Level of RVs, Machines, Furniture, Trailers, Tripods, Camera Equipment, Etc.Convenient 2 pack let's you mount in two locations or have a spare if you leave one somewhere. * A T-level lets you cross check accuracy by turning the level to compare to your marked measure. *These small handheld bubble T-levels can be permanently mounted to a counter in your RV or on your furniture/machine so you can always verify if it is still level (Note when mounting with screws, don't screw too tight or you can warp the back-screw in enough to hold but without making the heads of the screws flush inside the holes). *Use when hanging pictures. *This is very important when "leveling" your RV or items in your RV such as fridge. *Attach to the tongue or back bumper of a trailer or camper hitch to check level. *Attach to pool tables or ping pong tables for accurate play. *Use on machine tools ensuring safety when using. *Use when leveling telescopes or cameras or other tripod mounted devices. *Use at the firing range on a rifle rest. Each level has two screw holes for permanent mounting (Don't over-tighten screws).Some users prefer to use double-sided tape on the back but don't overlap as it will throw level off. We don't recommend the style that comes with a magnet on the back as it tends to make this "un-level".Each level consists of 2 marked vials with liquid mounted to a plastic triangular backing. A small level is so convenient to keep in your tool bag or on the go bag also as it takes up so little space and weighs so little. The holes are provided for screwing to a surface permanently, but some users use the holes to turn these into a string line level. Height 2 ¾" tall by 1 ¾" wide, one red, one black, includes 4 free screws for your convenience
