Weber Grill Review
Shortly after the launch of the Genesis 1-5 grills, Weber introduced a smaller two burner grill, the Genesis Jr.
The Genesis Jr was an interesting grill for several reasons. This grill is where Spider Stoppers were
introduced, served as the model for future two burner Weber grills such as the Genesis Silver and introduced
the cart design eventually utilized for the Genesis 2000-5000 series.
In US patent 4,829,978 titled “Gas grill with insect deterrent” (Erich Schlosser inventor) Weber describes a
problem encountered with gas grills in general. To quote, “One of the problems that has been encountered
is that nocturnal insects, such as spiders, tend to be attracted to the air inlet to the tube. These insects, and
in particular spiders, will crawl into the tube through the inlet and nest in the venturi restriction while
building webs which will severely restrict the flow of the gas and air mixture to the remainder of the tube. As
the tube becomes clogged or obstructed, gas is forced out of the air inlet where it can ignite and create a
severe fire hazard. Furthermore, any ignition of gas outside of the burner tube can melt the control knobs
since they are located in close proximity to the burner tube inlet.” This patent application was filed on
December 22, 1987, several years after the introduction of the Genesis 1-5 grills. I will make the assumption
that the early Genesis grills suffered from this problem.
The solution to the spider problem was the addition of a mesh guard around the venturi section of the
burner tube. These mesh guards, trademarked as Spider Stoppers, became standard equipment on all later
models of the Genesis grills. The Spider Stoppers required annual inspection especially since they were
made of plastic and could easily break.
There are two design features I find interesting about the Jr. The first is the location of the side table on the
right side of the grill. Other Genesis grills with only a single side table (Genesis 1, Genesis 1000) had the
table on the left side of the grill. It appears that Weber intended the protruding metal bars on the left side
of the Jr (which would make a perfect mounting bracket for a side table) to be used as handles for pushing
the grill around your deck or patio. The second feature of interest is that this is the grill where the expanded
cart is introduced. In the Genesis 1-5 grills as well as the Genesis 1000 series the cart extends from the left
side of the grill body to the right side of the grill body. In the Genesis Jr the cart extends from the left side of
the grill body all the way to the end of the burner control module. This cart design increases both the
storage area underneath the grill as well as the overall stability of the grill. This was a design feature
carried into the Genesis 2000-5000 grills.
Although Weber had been successfully selling the propane fueled Go Anywhere many years before the
Genesis line was introduced, the Genesis Jr was Weber’s first real attempt at a serious grill in the mid-sized
range. The two burner Jr had five long Flavorizer bars like the Genesis 1-5 but only six short ones instead of
the eight bars on the larger grills. (On a side note, the six short bars are accurately shown twice in the
owner’s manual for this grill but are inaccurately described as including eight in the text.) I do not have an
accurate number for the size of the grilling surface but I will estimate that the Jr offered about 350 square
inches. The side table, handle and storage area were all made from wood. Weber found there was indeed
a market for a good grill of this size and eventually replaced this Jr with the Genesis Silver and later with the
I would like to thank Brian Moriarty for the use of his picture of his Weber Genesis Jr.
