IMPORTANT – General and Safety Information
A. Only ERICO authorized materials should be used to make LENTON® INTERLOK Rebar Splices.
1. Do not splice except as detailed in the instructions.
2. Do not alter materials without manufacturer authorization.
3. Do not substitute for ERICO authorized materials.
Failure to comply with the above may result in hazards to the individual, improper splices, or damage to items being connected.
B. Make splices in accordance with described splicing procedures and in consideration of surrounding conditions and personnel.
Refer to the HY10L MSDS prior to beginning work with the grout.
1. Personnel should be properly trained in the use of this product.
2. Avoid breathing concentrations of grout dust as it may be hazardous to health. Refer to MSDS for control measures.
3. Avoid skin contact with grout slurry.
C. Unusual applications or conditions may exist which require special considerations.
1. Provide adequate ventilation where natural air flow is not sufficient to prevent personnel from breathing
concentrations of dust.
D.
Storage of HY10L Filler Material should be in a clean, dry, secure area and should be restricted to access by authorized personnel
only. Discard any torn, wet, or otherwise damaged bags. Discard any bags which have become wet or where material clumping
is observed. Material consistency should be that of a free flowing fine powder.
E. To determine the date of HY10L manufacture, refer to the lot number located on the end panel of each bag.
The manufacturing date can be determined as shown below:
X YY MM DD ZZ
Example A1210051J: Material produced October 5, 2012 batch 1 of the day. The 1st Alpha character “A” is a production
code. The last character “J” is an optional placeholder for the manufacturer (it may or may not be used and printed on
the bag).
DO NOT USE any HY10L which is in excess of 1 year beyond the manufacturer’s date noted on the package.
F. Refer to grout mixing directions located on the bag for proper mixing guidelines or contact ERICO.
G. Refer to Pump Fill or Gravity Fill Installation Instructions located in this Manual for proper installation guidelines.
H. The recommended temperature range of the HY10L Filler Material is 50 to 80°F (10 to 27°C). At no time during placing and
curing should the temperature of the coupler, rebar, and HY10L be allowed to be outside the range of 40 to 90°F (4 to 32°C).
I. Do not use more than 13.5% water by weight (0.8 gallons or 3.0L per 50 lb. (22.7Kg) bag) or obtain an ERICO Flow
Template reading of greater than 6.5” (16.5cm). Do not add any additives or admixtures to the HY10L.
J. Keep walls and panels undisturbed for at least 24 hours [at 68°F (20°C)]. Movement during curing will result in decreased
splice performance. Temperatures below 50°F (10°C) considerably increase the time it takes freshly placed grout to develop
strength. Therefore, there is a risk of damage or collapse if the structure is loaded before it develops adequate strength.
This

other grouts will void all warranties, whether expressed or implied.
L. While working on the job site, observe all Federal, State, and Local safety regulations.
1. Wear a hard hat and safety glasses.
2. Wear gloves to avoid cuts.
3. Prior to installing connections, read and understand all operating, mixing, and safety instructions found in this Manual
and on the HY10L bag.
M. Deviations from the specified recommendations outlined in this manual will void all warranties. It is the responsibility of the
user(s) to observe proper grouting conditions, (e.g., temperature, water to cement ratio, placing consistency, etc.)

WARNING
1. ERICO products shall be installed and used only as indicated in ERICO product instruction sheets and training materials. Instruction sheets are available at www.erico.com and from your ERICO customer
service representative.
2. ERICO products must never be used for a purpose other than the purpose for which they were designed or in a manner that exceeds specified load ratings.
3. All instructions must be completely followed to ensure proper and safe installation and performance.
4. Improper installation, misuse, misapplication or other failure to completely follow ERICO’s instructions and warnings may cause product malfunction, property damage, serious bodily injury and death.
The customer is responsible for:
a. Conformance to all governing codes.
b. The integrity of structures to which the products are attached, including their capability of safely accepting the loads imposed, as evaluated by a qualified engineer.
c. Using appropriate industry standard hardware as noted above.
SAFETY INSTRUCTIONS:
All governing codes and regulations and those required by the job site must be observed. Always use appropriate safety equipment such as eye protection, hard hat, and gloves as appropriate to the application.

Overview
The LENTON® INTERLOK Mechanical Reinforcing Steel Splice is designed to connect #5 (16 mm) through #18 (57 mm) rebar,
conforming to ASTM
the LENTON
®
taper threaded system in conjunction with a special
rial (grout). Assembly of the connection is normally
the coupler at a precaster’s plant prior to placement of concrete in the precast member. The connection is completed at
job site, where the exposed dowel of the adjoining panel is positioned within the interior of the coupler. The filler material

is
either poured or pumped into the cylindrical end of the coupler. The coupler can be oriented in either a vertical, inclined or
horizontal position.
The filler material is a special ready-to-use grout, designed to maintain fluidity for an extended period of time while achieving
a high-early-strength. It is a metallic, volume-stable, material capable of developing in excess of 8,500 psi (58.6 MPa)
compressive strength at 28 days. To ensure a proper connection, the addition of water must be maintained in strict
accordance with ERICO recommended procedures. In addition, the temperature of the grout during placing and curing must
be maintained within the recommended guidelines. Misapplication or use of grouts other than ERICO brand of HY10L without ERICO approval voids all warranties, both expressed or implied.
The coupler is produced as a casting and LENTON taper threads are machined under strict Quality Control guidelines. Taper
threading of the rebar ends are produced using ERICO’s equipment. Prethreaded bars can be provided from ERICO’s network
of threading centers, or by positioning a threader at the precasters plant. The threads are right hand and tapered to match
the accompanying coupler.
When assembled in accordance with ERICO recommended procedures, the splice will meet or exceed the ACI 318, BS8110,
AS3600, UBC
®
or IBC® Building Code requirements.
