1. Purpose

This is a visual guide to aid in the installation of the City Post anchor cups. This document covers the recommended procedures for installation.

2. Definitions/Tools City Post Assembly: The complete City Post assembly includes:

• Post – the taped final assembly

• Anchor Cup – Aluminum molded anchor that will be imbedded into the roadway

• Adhesive Shield – Clear sheet used to prevent epoxy from making contact with the post.

• Rubber Gasket - 0.20” rubber ring to seal the base and anchor cup

Core Drill : Any drill capable of accepting and centering a 2.1” minimum sized core bit.

Core Bit : Any masonry bit capable of creating cores a minimum of 2.1” in diameter.

Numerous Suppliers have bits: HILTI, Grainger and BOSCH, etc.

Epoxy/Adhesive : There are two adhesive systems approved for use: EAS-06 / FIRMmarker epoxy (for all surfaces) and Hilti HY 200 (concrete only). Please refer to the table below: all times are for a nominal 86oF; higher temps will result in faster times, lower temps will take longer to cure. Approximately 7 – 9 fluid ounces or 200 - 260 ml of epoxy for estimating for one install.

Work Time Cure Time Dispensing / Application EAS-06 / FIRMmarker 8 min 1 hr Qts./Gallon Hand Mixed & Poured EAS-06 / FIRMmarker 8 min 1 hr 20 oz. Cartridge / Gun Systems

Hilti HY 200A Hybrid

4 min 30 min Cartridge system / multiple guns

Depth Gauge : Disposable tool used as a stop point for epoxy fill, see below.

Protective Gear : Glasses, latex gloves, rag for cleanup, etc…. your list may vary.

3. Preliminary Preparation – CRITICAL for new installations

Ensure that the clear adhesive shield and the black rubber gasket are installed between the City Post and the anchor cup. Screw down the anchor cup tightly until it stops.

Installation Guide and Recommendations

This shows how to create a depth gauge to speed your process along in the field. There are several ways to mark the depth, this is one simple and effective way. Please refer to the table below to determine your fill depth of epoxy.

*SFD = Stop Fill Depth

For example: using a 2.25” core the adhesive can reach a maximum fill that leaves 1.61” of air space. The air space will be displaced by the anchor cup when inserted.

Making a simple depth gauge tool using a business card:

Layout Draw two lines to be cut per the SFD dimension shown above.

Cut Make cuts on the lines drawn.

Fold Fold flap back 90 degrees.

The flap of the card should match the stop fill depth required. When filling the core hole with epoxy, stop as soon as contact is made with the edge of the flap that is inserted into the hole.

Caution: Overfilling the core hole can result in the City Po st being permanently adhered to the roadway. Do Not Overfill.

Core - opening into which adhesive and anchor will be installed

4. Coring your Holes

Guidance – the suggested core depth is 3” (2” Cup) or 5” (4” Cup). The hole will leave a jagged bottom when the core is broken off. The extra ½” of depth ensures that the minimum depth of 2.5” or 4.5” is achieved.

Check Fit – Insert the assembled City Post into a dry hole, does it sit level, if not remove more material and recheck.

Clean – Holes must be free of debris and dust, blow them out with an air hose.

Dry – if using a wet bit core drill, ensure the holes are completely dry before applying adhesive.

5. Installing the Anchor Cup Using the Hilti Cartridge System

Tools needed to proceed:

• HILTI Adhesive dispenser – Manual or electric

• HILTI Adhesive and

• Depth gauge.

• City Post Assembly

Using the adhesive dispenser, evenly distribute the adhesive into the hole to keep air bubble/pockets to a minimum.

Fill to SFD depth shown in table above.

Insert the SFD gauge into the hole. It is critical to STOP the adhesive at contact with the gauge to ensure you do not over fill the opening.

This will give you a clean and installation.

Caution: Do not overfill.

Adhesive contact with the SFD gauge should leave a little adhesive on the edge of the flap.

Backfill the flights of the 4” cup with adhesive prior to installation.

Slowly, insert and rotate the anchor cup into the adhesive filled hole and twist one full turn.

Rotating the post spreads the adhesive evenly around the anchor cup. This is critical to get a good even distribution of adhesive.

Once final depth has been reached, no adhesive should be visible around the base.

Allow the anchor and epoxy to set up, refer to the adhesive manufacturer’s directions for cure time.

Once the adhesive is fully cured you can remove the City Post from the anchor cup. If the steps are followed correctly and in sequence you should have an installation that looks very similar to this.

Finally, tighten down the City Post with the City Post wrench.

This tool is also useful to loosen the City Post when it needs to be removed. (Wrench is sold separately).
