Installation of Reliance Foundry’s Model R-8430 Fold-Down Bollards
Fold down bollards can be easily surface mounted on existing concrete surfaces with a specialized mounting flange.
Installation Equipment Required
- Measuring tape
- 1" masonry drill bit
- 3/4" wrench
- Hammer (optional)
- Touch-up paint
- Hammer drill or rotary hammer
- Can of water for cleaning drill bits
- Chalk line
- 3/8" Allen Key (hex key wrench)
- Masonry Nail (optional)
Surface Preparation and Determination of Layout
* NOTE: Fold Down Bollards should be left in their packaging until the exact moment of installation
- Ensure that underground utility lines and pipes pose no risk.
- Clean surface. Dirt and debris can affect the line of sight and disrupt placement of the mounting. Use a broom, an electric leaf blower or a pressure washer to clean the surface of the concrete on which the fold down bollards will be placed.
- Study site plans. Site plans are generally created by the architect of the project. The architect will mark the intended location of each fold down bollard on the plan. Ensure that the plan coincides with the site and familiarize yourself with the intended location of each mounting.
- Measure the placement of each fold down bollard. Use chalk to mark the centre point of each fold down mounting. Many contractors find it beneficial to snap a chalk line to achieve a uniform look if the fold down bollards are intended to be placed in a row.
- Mark the position of the hinge and designate your hole-markings. Place a fold down mounting over each chalk marking so that its middle coincides with the centre line. Use chalk to create drill-markings for each bolt.
Drilling the holes
- Create pilot holes for the concrete inserts. Assuming the bollard is in the place where you want, use a small masonry chisel to tap a starter pilot hole in the centre of each hole marking. This will prevent the rotary hammer from drifting while boring the hole.
- Set the depth control on the hammer drill (or rotary hammer) to 3-5/8”. Most hammer drills have a depth setting or depth control bar. If depth control is not available, use masking tape to mark 3-5/8”on the masonry bit.
- Drill the hole. Apply force to the rotary hammer and create a hole that has a one inch diameter and a depth of 3-5/8”. Drill on high speed, using the hammer function if available. Check the masonry bit often to ensure it remains debris-free. If the masonry bit becomes clogged with concrete dust, rinse it in the can of water. If an overly hard patch of concrete is encountered, it can be broken with a masonry nail and hammer.
Securing the Fold Down Bollard
- Insert a concrete insert into each hole. Ensure that perforated side faces the below-ground substrate and the top of the anchor sits ½” lower than the surface of the concrete.
- Set the fold down mounting over the holes. Place the mount over the freshly drilled holes. Place washers over the holes found on the fold down mounting and set the bolts into place. Tap the heads of the bolts with a hammer in order to secure the concrete inserts and then use a ¾” wrench to tighten the bolts. Tighten the bolts evenly in a cycle, similar to how one tightens lug nuts on a car’s wheel.
- Inspect the installation. Check the bollard and its mounting for any signs of surface damage. If either were scratched or scraped during installation, they can be repaired with touch up paint, commonly found at automotive stores. Abrasions must be covered to avoid rust and ensure the proper life of the fold down bollard. See further details under CARE AND MAINTENACE.
