The SENTRY Retractable Bollard range features both electric and manual operated options. This range stands alone in the industry. The all electric design with a wide range of crash ratings and aesthetic options is the number one choice for architects in designing first class buildings and gaining LEEDs certification by contributing up to five categories. Security and system integration are easily tackled with the robust PLC and VFD output capabilities of the SENTRY Retractable Bollard solution. The manual version has similar features and is unique in the fact that it can be upgraded to electric operation at any future time if required.
