Purchase Drop-In Anchors

Red Head manufactures and sells the Multi-set, which is a drop-in anchor. One of the Multi-set drop-in anchor styles is called the RL. This anchor is an internally threaded anchor designed for use in solid concrete and is manufactured without a lip. It can be used below the surface of the concrete at deeper embedment to allow potentially better performance. The RL drop-in anchor is considered a heavy duty anchoring system and is a shell type anchor made from steel with an internal expander plug sealed within the shell. Multi-set RL anchors are manufactured from zinc plated carbon steel, 18-8 stainless steel, and 316 stainless steel.

Multi-set RL Approvals & Listings

The multi-set RL drop-in anchor meets or exceeds:

US Government G.S.A specification A-A-55614 Type 1 (formerly GSA: FF-S-325 Group VIII).
Underwriters Laboratories
Factory Mutual
City of Los Angeles - #RR2748
California State Fire Marshal
Caltrans

Multi-Set RL Features

The expander slots that are cut into the shell of this concrete anchor at the opposite end of the threads allow for easy setting and superior performance. The cone insert is designed to expand the Multi-set RL anchor from the inside.

Multi-Set RL Features

The expander slots that are cut into the shell of this concrete anchor at the opposite end of the threads allow for easy setting and superior performance. The cone insert is designed to expand the Multi-set RL anchor from the inside out when set by using a hammer and setting tool.

Multi-set RL Rust Resistance

With three different materials to choose from, this anchor can be chosen to meet any rust resistance requirements. For indoor use with no moisture present, the standard zinc plated carbon steel anchor is suitable. If the application calls for the anchor to be placed outdoors where moisture and other chemicals are present, then the 18-8 stainless steel version should be used. For extreme rust resistance, the 316 stainless steel drop-in works well even when submerged in salt water and other corrosive environments.

Multi-set RL (Other Choices)

The Multi-set RL drop-in anchor is just one style of the multi-set drop-in anchors that are available. The RM version comes with a lip designed for controlled embedment depths. The RX version is specifically designed for use in hollow core precast or post tension concrete. The CL version of this drop-in anchor has internal coil threads for use with coil thread bolts.

Multi-set RL Internal Threads

The RL Multi-set drop in anchor has internal national coarse threads that extend about 1/3 of the total length of the anchor. They are designed to accept any bolt or threaded rod with the matching national coarse threads. The 1/4" has 20 threads per inch, the 3/8" anchor has 16 threads per inch, the 1/2" has 13 threads per inch, the 5/8" has 11 threads per inch and the 3/4" anchor has 10 threads per inch.

Multi-set RL Drop-in Anchor Embedment Depth

Each diameter of this drop-in anchor comes in one length only. The length of the anchor is the minimum embedment that the anchor should be placed into the concrete. The RL version of this anchor doesn't have a lip, which allows for deeper embedment and possibly better performance.

Multi-set RL (Expanding the Anchor)

All mechanical type anchors must be expanded once they are placed in the hole of the base material. Using a setting tool designed for each specific diameter will effectively set the drop-in anchor. For the RL drop-in anchor to be expanded properly, the lip of the setting tool must meet the lip of the anchor.

Multi-set RL Hole Diameter

The size of a multi-set Rl anchor is designated by the internal thread, or by the diameter of the bolt or threaded rod that can be threaded into the anchor. The outside diameter is larger than the designated diameter and equals the diameter of the hole that must be drilled. A 1/4" anchor needs a 3/8", 3/8" a 1/2" hole, the 5/8" needs a 7/8" hole and the 3/4" needs a 1" hole. These holes must be drilled using a hammer drill and a carbide bit that meets ANSI standards B212 15-1994.

Multi-set RL Drop-in Anchor Installation

1. Drill a hole in the concrete using a hammer drill and carbide tipped bit meeting ANSI standards. Make sure the depth of the hole is at least deep enough to meet the minimum embedment depth for the anchor being used.

2. Remove all dust and debris from the newly drilled hole before proceeding in the installation process.

3. Drop the anchor into the hole and tap with a hammer if needed until the anchor is flush with the surface of the concrete.

4. Insert the concrete setting tool for the diameter of the anchor being used into the internally threaded end of the anchor. Strike the setting tool with a hammer until the lip of the setting tool touches the lip of the anchor.

Always use personal protective equipmentAs with any anchoring project, it is important to keep safety in mind and follow instructions carefully. Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete fasteners. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project.
