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.

Center Hung

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.

Offset Hung

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.

Return Miters

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.

MITERED DESIGN
1-1/8" mitered end standard.
Extended mitered ends available -specify length.

Straight Ends

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.

STRAIGHT END DESIGN
Extended straight ends available -specify length.

Bevel Cut Thresholds

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.

Scribing
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 Strip

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.

No. 200 Stop Strip (offset Hung)

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.

No. 201 Stop Strip (Center and Butt Hung)

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.

No. 301 Step Down Strip

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.

Thresholds for Overhead and Surface Door Closers

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.

Anchoring

Thresholds are drilled for installation. They are furnished with concrete anchors as standard. If machine screws and expansion shields are required, specify "MSES".

Sizes

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.

Extra-Wide Thresholds

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.
