1.
Q. Where can I use the EZ Stairs system?
A.
The EZ Stairs system is intended for:
• interior stairs
• exterior stairs
• concrete formwork
The EZ Stairs brackets are adjustable and they're designed
for use in straight stair runs only.
2.
Q. What skill level do I need to build this stair?
A.
The EZ Stairs adjustable brackets greatly simplify
stair building. Traditional stair making requires some of
the most skilled craftsmen in the industry. However, with
EZ Stairs, if you:
• have a basic working knowledge of power tools and safety
issues.
• follow the instructions carefully and check your local
building codes
You should beable to build a stair using the EZ Stairs System.
3. Q. What do I need ?
A. Screws and wood (or other
material depending on application) click.
4.
Q. Will I save time using the EZ Stairs system?
A.
Tests have shown that construction
time for the EZ Stair system is close to half of the time
required for conventional construction.
5.
Q. What if I make a mistake in layout?
A.
With the EZ Stairs system, mistakes can often be corrected
by backing the screws out and readjusting the brackets. With
conventional construction, mistakes are fatal. You have to
throw out the material with the mistakes and start all over.
6.
Q. How strong is the EZ Stairs system?
A.
Independent engineering tests have shown the EZ Stairs construction
to be much stronger than conventional construction. In a test
of an 8' wide stair, a load in excess of 9,200 lbs. was applied
to a tread before breaking. There was no damage to the brackets-
that's strong!
7.Q.
What about safety and quality?
A.
The EZ Stairs brackets have been constructed from heavy duty
galvanized sheet steel. We have taken much care to ensure
that the product exceeds all the strength requirements of
the uniform building code and a quality assurance program
is in place to guarantee the highest standards in quality
and safety. Review

8.
Q. Building codes?
A.
Building codes vary city to city, county to county and state
to state. It's wise to check your local building codes. The
EZ Stairs brackets exceed the strength requirements as set
out in the uniform building codes and may be adjusted to meet
any dimensional requirements for risers and treads. Also check
your local codes for any fire requirements. Refer
code officials to ICC Evaluation Service Report ER-6161.
9.
Q How do I adjust risers and treads?
A.
The risers are adjusted when the brackets are rotated (pivoted).
This allows infinite adjustment of the riser between 0"
and 8 1/4" in height.
The tread width is adjusted
by use of the adjustable spacer. The tread width adjustment
is not infinite (as with the riser), but is incrementally
adjusted. The spacer has 13 settings marked "a"
through"m" which varies the tread width. The spacer
setting chart is used to find the setting which is closest
to the desired tread width. The riser height/tread width should
be checked before final fixing of the stringer.

Q.
How do I do an initial 2x6 stringer set-up
with a gap
closure?
A. When you adjust (pivot) your brackets
to your customized rise requirement, a gap will generally
still remain between the 2x6's. Many builders leave this
gap for drainage purposes. However, many prefer the gap
to be closed. To close the gap between the 2x6's, during
the initial stringer assembly, follow these instructions
(after you have determined what your desired rise and tread
need to be and you've pivoted brackets into position).
:
Insert 2 additional screws into the bottom bracket 2x6 member,
then remove the top pivot screw in the top 2x6. Close the
gap....the brackets will not move out of position. When
the gap is closed, insert all screws into the pre-marked
holes except your first bracket and last in
the run you're building. The reason for not inserting these screws at this stage is
that these 2 brackets will normally need to be rotated out
of the way, for the 3 to 4 quick skill cuts that will be
required to complete your stringer.
11.
Q. How long and wide can I build the stairs?
A.
The EZ Stairs system is designed for stairs up to 9' in width,
for interior stairs and 7' in width for exterior stairs, using
the two outside stringers only. The stair length will require
supports at certain intervals along the stringers length.
These support intervals vary with the stair width (see instructions
in box).
12.
Q. How do I set the spacer?
A.
Once the spacer setting position has been selected (see spacer
setting chart in box directions), simply remove the setting
screw and reposition the spacer extension with the setting
screw in the appropriate marked setting hole ("a"
through"m"). Tighten the screw to set the spacer.
13.Q.
How do I decide the riser and tread size?
A.
The minimum and maximum riser and tread sizes are determined
by your local building codes. You must set the risers and
treads within these limits..
The medium riser size is around 7"
and may vary up or down from this figure. Normally the measured
stair height is divided by 7 and to determine the number of
riser spaces required. The measured stair height is then divided
by the number of risers to determine the riser height. If
this figure does not fall within required parameters, riser
spaces may be added or subtracted until a satisfactory riser
height is achieved.
The medium tread width (run) is 10"
to 11" and may vary according to code and/ or stair length
restrictions. Stair length restrictions may limit the overall
stair length and treads width may be determined by dividing
the stair length by the number of treads. If stair length
restrictions do not apply, a tread width not exceeding 11"
is recommended as this will allow the use of treads cut from
standard dimension lumber i.e.- 2 ›‹ 12
(1 1/2" ›‹ 11 1/4" finished size).
The adjustable spacers are supplied
with the spacer setting at "g". This will give a
riser height of 7" and a tread width of 11". If
the riser is set higher than 7", the tread width will
decrease and if lower than 7" the tread width will increase.
