Impact KG Vari-Angle Overview

The Keygrip Pro Vari-Angle 4" Caster Set from Impact adds mobility to any light stand with 1" square leg tubing. The unique adjustable design can match any leg angle, and the casters securely carry maximum loads on a wide variety of baby, combo, and slider stands. Spring-loaded 5° rosettes ensure matching angles and solid locking that won't twist or move regardless of the load mounted on the stand. The caster's thick 4" rubber wheels glide easily over most surfaces, including thick carpeting.

Each caster features an integrated bubble level for rapidly leveling the caster so it's level with the floor regardless of the leg angle. A scale with 5° increments lets you note the caster's angle to easily and precisely set the same angle on the other two casters. The KeyGrip SA-PVA4CS-26 robust aluminum and steel vari-angle casters are precision manufactured to exacting standards and specifications for video, photo, and cinematography applications.

Adds Mobility to Most Pro Light Stands
Baby, combo, and slider stands all benefit from adding wheels to make moving and positioning much faster and easier. The SA-PVA4CS-26 caster set is compatible with stands with 1" square leg tubing because you can adjust the wheels for any leg angle.
Vari-Angle
The casters can be adjusted and set to any angle level with the floor to level your stand. Simply loosen the angle lock and adjust the wheel's angle until the integrated bubble level shows that it is parallel to the floor.
Angle Scale
5° increments are etched into the angle lock's metal chassis. Once one of the casters is leveled, the scale makes it easy to set the other casters at identical angles so that your stand will be perfectly level with the floor. Spring-loaded rosettes create a firm grip that won't slip or move throughout your shoot or session.
4" Locking Rubber Wheels
The 4" wheels will glide over most surfaces, including thick carpeting, so you can easily move a stand to a new position. Foot-operated wheel locks ensure stability while you shoot.
360° Rotation
Each wheel swivels a full 360° so you can effortlessly move a stand in any direction to reposition lights and gear with ease.

Heavy Duty casters that turn pro stands into mobile ones

By Jim
Rated 5 out of 5
Date: 2026-04-17

These caster wheels are a fantastic upgrade for any heavy duty light stand. Being able to take a solid, pro level stand and make it mobile is a huge convenience, especially when you are working in a studio and/or constantly repositioning lights. It saves time and effort and makes adjustments during a shoot much smoother. What really stands out is how strong and well-built these are. Once they are locked in place, they feel extremely secure and stable, even with heavier gear mounted. I appreciate that they are designed to match the angle of the stand legs, which makes everything feel balanced and safe. It is not just about adding wheels, it is about doing it the right way. The wheels themselves roll very smoothly and handle different surfaces without any issues. Locking them down is quick and reliable, so once you are in position, nothing moves. This is a very well-designed accessory that adds a lot of functionality to your stands without sacrificing stability. [I have received this product in exchange for my honest review.]
