Rixson® thresholds add the finishing
touch to the concealment of floor closers
and pivot sets.
Unlike standard thresholds supplied as
part of a weatherstripping package,
Rixson thresholds have preparations for
spindles, adjusting values and separate
floor plate sections to allow maintenance to the floor closer without disturbing the
entire opening.
ANSI 117.1 and A.D.A. requirements are met with 1/4" high thresholds.
Prefix "PH" to 400, 500, 600, 700, and 800 in aluminum and PH 700
and 800 in bronze. The PH designation must be put in threshold description.
When ordering with PH floor closers it is not assumed PH threshold is necessary.
ANSI 117.1 and A.D.A. will not allow over
1/2" total threshold height.
Abrasive coating may be added to increase
sure footing for handicap situations.
When ordering section B, advise hand,
type (only used on 1 and 4), width (400,
500, 600, 700, 800), height 1/2" or PH
1/4", if dimensions other than standard
(see chart on page 172), material
(aluminum, bronze, or stainless steel).
Section D specify type of closer, closer
features that affect valving (SHO, AHO,
NHO, DA) type (1, 3, 4, 5) width (700,
800) if stop strip, height 1/2" or PH 1/4",
if dimensions other than standard (see
chart on page 173). Offset (3/4 or 1-1/2)
Section A advise opening size, single or
pair of doors, type (1, 3, 4, 5) width (400,
500, 600, 700, 800), if stop strip, height (1/2" or PH 1/4"), type of closer, type of
material (aluminum, bronze, or stainless steel). If single door opening, if miter
is required.
See previous notes for section A and D.
When miters are ordered for replacement,
specify section material (aluminum, bronze, or stainless steel) and hand. Standard
miters are 1-1/8" –- advise if different width is required. Lengths
other than those on page 173 must be noted.
Furnished on the pull side of the door. The return miter at the
spindle side of the doorway is detachable for easy removal of
closer plate section. Four corner miters, to enhance finished
appearance, are available upon request.
1-1/8" mitered
end standard.
Extended mitered ends available -specify length.
When the threshold abuts a wall at the ends, straight ends up to
2" can be substituted for mitered returns at no additional cost.
Provides a continuous, finished appearance.
Extended straight ends available -specify length.
Standard width thresholds can be straight rip cut to achieve a flush
floor condition. The threshold bevel on the interior side of the door
is removed; permits threshold and carpet (or tile) to meet at the
same height. A 5/16" bar support (provided) or built-up concrete
sill is required. Dimensional details required.
Cutting the threshold to fit the door stop is done on the job.
Rixson® will do scribing only if accurate dimensions are supplied.
Cost is extra, depending upon details.
(Drawing indicates number of cuts required to complete
various scribing operations.)
Stop strips are furnished at extra cost, when specified. On single acting doors, a stop strip is recommended to serve as a weather
seal on the push side at the bottom of the door.
For use on threshold cut for all floor and overhead concealed OFFSET TYPE
closers and pivot sets. This adds 3/8" to width of threshold. Where 200
stop strip is used, it is always applied to the bevel on the push side of the
threshold.
For use on thresholds cut for all floor and overhead concealed CENTER HUNG
single acting closers, CENTER HUNG pivot sets and BUTT HUNG floor closers.Where
201 stop strip is used, stop strip is always applied on tread surface of threshold
on push side, not on the bevel.
Designed to accommodate sill conditions where the floor drops 1/2" below
sill height. Add 1" to width of threshold. Step down strip may be applied
to either push or pull side of thresholds. Not available on Type 5 thresholds.
Straight threshold lengths, with or without 1-1/8" mitered or straight
ends, are available for Nos. 700, 800, and 0700 overhead concealed closers,
or any manufacturer's surface and overhead concealed closer.
Thresholds are drilled for installation. They are furnished with concrete
anchors as standard. If machine screws and expansion shields are required,
specify "MSES".
The width of the threshold must be sufficient to completely cover the closer.
All cover plates (or "D" section) must be 6-3/4" or 7-3/4"
wide. Narrower types may be used where overhead concealed or surface closers
are being supplied. On 500 series thresholds, the cover plate section is furnished
with 6-3/4" or 7-3/4" cover plate (D Section) and 3-3/4" or 4-3/4"
center (A Section).
Height will be 1/4" when physically handicaped (PH) is
specified.
Special widths of 8-3/4", 9-3/4", 10-3/4", 11-3/4" or 12-3/4" are available on request. A 5/16" x 1-1/2" center
bar support is provided as standard. Detailed dimensions required. Not available
with Type 5.
