The model R-8421 retractable bollard can be installed on pathways to deter intrusion, divert traffic, and define routes or roadways. It features a design that can be installed to match Reliance Foundry's model R-8410 fixed stainless steel bollards and model R-8412 removable stainless steel bollards. A complimentary, powder-coated model R-8421-RA retractable bollard version is also available. Because the model R-8421 can be collapsed into the ground it does not require any additional storage space. Please note that the model R-8421 retractable bollard can only be locked in its extended position.
