For trade shows, RJW Barnabas Healthcare Arena has 19,939 sq ft (1,852.4 m2) of space.

The facility hosted many well-known musicians and bands, including: KC and the Sunshine Band, Meat Loaf, Joan Jett and the Black Hearts, LeAnn Rimes, Hilary Duff, Carrie Underwood, Gavin DeGraw, and Daughtry, among others.

In March 2019, the arena hosted the NJSIAA Tournament of Champions for girls' and boys' basketball.

The facility has seen a marked decline in public events, outside of school-related games, since March 2020, due to the COVID-19 pandemic.

In the wake of a bribery scandal, culminating in Ritacco's arrest by the FBI on October 21, 2010, the school district quickly acted to remove his name from the building, opting to call it the Poland Spring Arena instead.
