One Systems Natatorium - Manual (Page 15)

The 112/NAT and 108/NAT must be mounted by drilling thru the entire grout filled
block as shown below. It is necessary to drill completely thru the grouted block and
run the 3/8”-16 AL6XN all thread thru the block. Large AL6XN backing plates for
structural support are required. The front and back sides of the block are shown in
the images below.
The drilled hole should be thoroughly cleaned prior to inserting
the 3/8”-16 AL6XN all threaded rod.
IMPORTANT NOTE: THE HOLE MUST BE DRILLED STRAIGHT. INSURE THAT
THE HOLE IS NOT DRILLED AT AN ANGLE. THE NORD-LOCK WASHERS AND
NUTS MUST BE FLAT AND PARALLEL WITH BOTH THE U BRACKET AND
BACKING PLATES FOR THE NORD LOCK WASHERS TO FUNCTION
PROPERLY. INSURE THAT THE HOLE IS NOT DRILLED AT AN ANGLE!
Consult with someone with experience drilling into grout filled block walls!
The front side is shown in the image below. This image shows the block wall and
NAT U-bracket.
SEE PAGE 13 FOR PROPER LOCATION OF THE BRACKET ON THE WALL IN
THE SECTION LABELED “BRACKET LOCATION ON GROUT FILLED BLOCK
WALLS”!
The rear side of the mounting configuration is shown in the image below. Note the
required use of the large AL6XN “backing plates”. These plates MUST be used.

BACKING PLATE LOCATION NOTE: Insure that the backing plates touch a single
block only! Do not allow the backing plates to bridge across to a second CMU block!
