Installing Benches using a Drop-In Anchor
Drop-in insert installation is recommended for site furnishings such as benches.
Drop-in anchors should only be installed in fully cured concrete that is at least 4" thick. All measurements in this installation guide assume a bare, level concrete surface.
Assembled Bench parts #1 through #5 (parts may differ depending on bench model)
½" Drop-in Concrete Anchors #6
Hex Head Bolts #8
1/2" Masonry Drill Bit
3/4" Insert Setting Tool (or equivalent)
1-3/8" Socket Wrench
3/16" Hex Key
Hammer Drill or Rotary Hammer
Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before drilling.
Clean the surface
Dirt and debris can affect the line of sight and disrupt placement of the bench.
Use a broom or pressure washer to clean the concrete surface prior to bench installation.
Study the site plans
Site plans are generally created by the architect of the project.
Refer to site plans, or place the bench where is to be installed, and mark the locations of each anchor.
For secure installation, ensure there is a minimum radius of ¾" of solid concrete around each mark.
Drill the holes
Create pilot hole
Tap pilot divot hole in the center of each mark.
This will prevent the hammer drill or rotary hammer from drifting while boring the hole.
Set the depth control on the hammer drill (or rotary hammer) to 2"
If depth control is not available, mark 2″ on the masonry bit.
Drill the hole
Drill a hole that has a 1/2″ diameter and 2" depth.
Drill on high speed, using the hammer function if available.
Check the masonry bit often to ensure it remains free of debris.
Secure the bench
Clear the hole
Clear the hole of all debris and/or standing water using the vacuum.
Tap the drop-in insert into the hole
With the slotted end facing down, drive the drop-in insert (A) down until its top sits flush with the concrete surface.
Ensure that the top is perfectly level.
Set the concrete insert
Insert a setting tool (B) into the threaded hole, then hammer down.
If a proper setting tool is not available, an equivalent flat-end punch can be used.
This will cause the internal expansion plug to set the concrete insert in place.
Place the bench
When ready to install, remove the bench from any packaging.
Place the bench over-top of the holes and confirm bench is level.
Maneuver it so the center lines up with the threaded hole in the concrete insert.
Lower the threaded bolt and tighten
Place the washer over the threaded bolt.
Lower the threaded bolt through the bench base.
Tighten by hand until it is secure in the concrete insert.
Inspect the installation
From a distance, examine the plane of view.
Ensure the bench is level.
Check the bench for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bench. For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.
Care and maintenance
Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance Foundry’s benches are finished with long-lasting powder coating. In most North American environments, routine inspections and cleaning will ensure that benches retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.
