Delineator posts by FlexStake combine both flexibility and tensile strength into one sturdy package!

These plastic posts are an ideal tool for dividing roadways and keeping traffic lanes tidy. They’re brightly-colored and tall, which makes them easy to see and difficult to ignore. They’re impact resistant, which gives them a relatively long lifespan. And they’re supple enough to snap back into position upon impact (instead of simply shattering), which promotes better safety for construction workers and motorists alike.

FlexStake SM700 posts feature a four-part assembly (the post and hinge, the base, the grips, and the mounting pin) that allows for easy installation and maintenance. All parts except for the base itself can be repaired or replaced without removing the base from the installation site. Crimped or squashed posts can be quickly fixed using the included repair kit.

Standard post colors are white, red, orange, yellow, green, blue, brown, and gray. Speak to a Transline representative for information on special ordering posts in custom colors (and lengths). Posts can be further customized with reflective sheeting in white, red, orange, yellow, green, or blue. Barricade striping and other patterns are available on request. Posts may also be fitted with custom signs and labels.

How to Use

FlexStake posts can be installed on concrete, asphalt, or even wood. To ensure a sturdy hold, the base should be attached to the desired surface using lag bolts, butyl rubber, or epoxy adhesive. Please note that, while repair kits come in all standard post colors, a perfect match for custom-colored posts may not be available.
