Drywall Jack

A drywall jack props and supports drywall sheet panels during ceiling installations.


The drywall jack is an engineering control that may help reduce overhead work during drywall ceiling installations.
A FastCap drywall jack uses a single, spring-locked telescoping pole. The T-JAK® uses a steel shaft, an inner threaded rod and a quick tilt knob that locks into place for precision adjustments.

FastCap® makes a group of jacks called the 3rd Hand Family.  The 3rd Hand HD (figure 1) consist of a pole that telescopes from 57 to 144 inches (12 feet) and has a load capacity up to 150 pounds.

The T-JAK® Drywall Tool (Figure 2) features a steel shaft,  a threaded steel rod and a quick-tilt knob.  The  T-JAK® tool slides from 53 inches to 108 inches supporting  objects weighing up to 400 pounds.  By tilting the quick release knob, the threaded rod can be raised to the desired supporting height. The knob will automatically drop and lock into place, engaging the thread. Final precision adjustments can be made by turning the quick release knob. Available accessories include extensions in 1 to 3 foot lengths  and drywall support brackets.

Risks Addressed:

Overhead work can cause musculoskeletal disorders (MSDs) such as shoulder muscle strains; tendonitis, which is inflammation of the tendons; or rotator cuff tears, which is a rupture of a shoulder tendon. The drywall jack can help reduce overhead holding by supporting drywall during installation.

How Risks are Reduced:

A drywall jack reduces overhead work because it supports the drywall being installed, allowing easier installation and increases the installer’s ability to take breaks during installation.

Safety and health experts believe drywall jacks will help reduce exposure to overhead work since the material is held in position by the jack.

Effects on Productivity:

A drywall jack may increase productivity by allowing more drywalls to be installed due to the ease of positioning and holding the drywalls.

Additional Considerations:

While drywall jacks reduce several risks, improper use of the jacks could be harmful.  It is critical to operate the jacks according to the manufacturers’ instructions.
