Quickly and easily regulate traffic and parking access
Retractable (or "telescoping") bollards can be retracted fully below ground, eliminating the need for additional storage and labor to remove and transport detachable bollards. When retracted, bollards close flush to ensure no obstruction or tripping hazards.
A single key-locking mechanism makes for quick and easy adjustments between extended and retracted positions. R-8400 series bollards feature a stylish, stainless steel design that can also be configured with fixed or removable mountings.
Factors to consider when installing retractable bollards
Retractable bollards are made from 316-grade stainless steel, ideal for withstanding corrosion and weathering. Stainless steel makes for stylish landscapes and is compatible with a range of contemporary designs. Bollards can also be powder-coated for additional visibility or to match existing buildings or landscapes.
Retractable bollards are mechanical devices that require proper planning, installation and maintenance to ensure long-term functionality. Cold and wet climates in particular require special attention be paid to effective drainage to avoid corrosion and seizing.
Site evaluation: Without proper drainage, high-moisture environments can lead to corrosion and limited retractability, or seizure, of bollards. Wet climates or areas with high water tables can lead to excess pooling, which can corrode receivers and retracted bollards. In below-freezing temperatures, pooled moisture will ice and seize retracted bollards or prevent from retracting. If installing in high-moisture environments, additional drainage or a sump pump may be required. Threaded drain holes are available for installations using a sump pump. Consult a geotechnician if you have questions about the suitability of retractable bollards for your intended site of application.
Planning installation: Proper installation is critical to the functionality of retractable bollards. Installation holes should be dug at a minimum of 60 inches with a diameter of 14 inches. The receiver will sit 4 feet below the surface, and the remaining 12 inches should be used for drainage. Installation holes can also be connected by a drainage ditch for better moisture removal. A concrete berm should be created around the top rim of the receiver to prevent moisture from penetrating internal housing. Site planners should choose a reputable contractor or construction firm to plan and install retractable bollards. Installation details and video are available at the retractable bollard installation page.
Regular maintenance: Retractable bollards can be disassembled and serviced if needed, but removal is not required if bollards are regularly maintained. Bollards should be kept dry, free from debris and properly lubricated. Bollards should be wiped regularly and surrounding areas swept to remove any dust and debris. Bollard assemblies should be lubricated regularly with an all-purpose lubricant and assembly grease. Any signs of rust should be removed as soon as possible. More frequent care may be required in more dusty and dirty areas.
*A raised concrete shoulder, or berm, will prevent moisture from accumulating in the bollard's receiver. **Threaded drain holes allow piping or tubing to be connected to the receiver (available upon request).
Convenient and unobtrusive
Compared to other removable options, retractable bollards eliminate the need for additional storage—saving both time and space. Retractable bollards are ideal in locations where uneven concrete surfaces won't allow adequate vehicle clearance over fold-down bollards.
Quick access control
Retractable bollards feature sleek access control to manually raise and lower bollards. Extended bollards provide clear visual barriers to restrict vehicle access, while allowing short- or long-term passage when lowered. Bollards can be secured in both raised and lowered positions with a single key-locking mechanism.
