How using pivots can affect your ADA compliance ?

muzzz — Thu, 26 Mar 2015 13:05:59 +0000

In the door and hardware industry “Clear Opening” is a very familiar term but also a familiar peril. When designing entrances that meet ADA standards, there are a lot of small details to pay attention to. The one we are going to look at today is opening width and how it is affected by your choice of offset pivot.

Here is a drawing to show how much an offset will affect a clear opening. It is a good visual for your customers.

This information is significant when dealing with ADA openings.

For ADA, there must be a clear opening of 32″. “Clear opening” includes the frame stops. Door hardware also affects the opening but, for hanging means, this data is critical.

With a 3/4″ offset pivot, the distance from rabbet to the face of a 1-3/4″ door is 3-1/4″. Add to that the frame stop on the lock edge of 5/8″ (most common stop size). You will be deducting 3-7/8″ from the 36″ opening. So, your “clear opening” is 32-1/8″. The door complies.

When there is a pair of 36″ doors, using a removable mullion, verify the width of the mullion being used. The type of mullion, below, only undersizes the opening 5/8″. The same as a single door opening with a frame stop. So, the opening is in compliance.

However, if it is a tube mullion, it sits behind the doors and is 1-1/2″ to 2″ wide. They make the opening smaller. 1-1/2″ will result in 32″. For a 2″ model, the opening will only be 31-3/4″. Therefore an offset pivot, will not allow the opening to be in accordance with ADA requirements.

1-1/2″ offset will not work, at all, for a 36″ door.
These references are for 36″ doors. Wider doors will meet ADA standards.

This information is, also, for 1-3/4″ doors. If the doors are thicker, the 36″ opening will not fulfill the requirements, with any offset pivot.

Take away from this is that if someone asks the question about how far the door sits in the opening, ask if they are trying to meet ADA and how wide the door is. If it is a pair, what type of mullion?

Why your door closer doesn’t work in extreme cold weather?

Murray — Mon, 02 Mar 2015 15:27:54 +0000

Baby, it’s COLD outside!!!!!!!!!!

The extreme temperatures that Southern and Eastern Canada have been experiencing lately have prompted quite a few calls to our TPS group. Most of the comments center around door closers not working well, either not closing or very slow to close. Facts are, in extreme temperatures, hydraulic fluid struggles to keep the viscosity required to allow the smooth and consistent operation of a door closer. At extreme low temperatures, some fluids can even reach the point where they actually congeal and will no longer flow. Thankfully, NORTON door closers have the answer with NorGlide® closer fluid.

NorGlide® closer fluid is a specially formulated multi-viscosity hydraulic fluid that contains “lubricity” and anti-oxidation agents that provide optimum performance and efficiency. This fluid complements the interaction of the door closers housing with its steel and brass components while maintaining stable viscosity to allow the door closer to perform in temperatures ranging from extremely high to as low as -40 C

It’s a good idea when choosing a door closer to keep weather conditions in mind, not just winter but the extreme heat of summer as well.

Murray — Thu, 29 Jan 2015 13:09:06 +0000

CORBIN RUSSWIN is pleased to announce the introduction of LASER ENGRAVING to its product lineup. Laser Engraving allows the client to “personalize” their hardware whether it be levers, escutcheons, paddle trim or exit devices.

The following slides show examples of Laser Engraving and the placement of the letters/numbers or a combination of.

A dedicated approval form must be filled out by the client and sent to customer service for submission to the factory for approval. There will be a “one time” set up fee assigned to the engraving process which carries a number or code that resides with the order and is required for future reference in the event additional product is required. Additional charges for each letter or number will apply.

We are very excited about this new engraving process which takes architectural hardware to a new level in esthetics. If you have any questions on this or any AA product, please contact us.

How to identify Sargent door closer manufacturing dates

Murray — Mon, 12 Jan 2015 15:55:50 +0000

Greetings friends and HAPPY NEW YEAR!

I wanted to start off the New Year with an installment on how to correctly identify the manufacturing date of a SARGENT door closer. We covered some of this in a previous installment but I have new information to add to this to help you not only identify the manufacturing date but also to help you identify the model by the “foot print”.

For those of you who know door closers well, you will understand what I mean by a “foot print”. This is the real estate the closer body actually takes up on the surface of the door or frame and identifies the distance between the centers of the mounting holes, depending on the application of course.

Please see illustrations following this short intro which speaks to both identifying the manufacturing date AND the “foot print”. These are very important details that will help us help you in identifying the closer in question but most important, will tell us if the door closer is still within the warranty period.

281 – Month and Year
ex. 1206 = DEC 2006
351 – Week and Year
1431 – Week and Year
ex. 1706 = May 1, 2006

1331 – Month and Year
1130/1131 – Month and Year

Month = A – Jan Thru L – Dec
Year = S-2015, T-2014, U-2013
V-2012, W-2011, X-2010, Y-2009, Z-2008, A-2007, B-2006
C-2005, D-2004, E-2003, F-2002, G-2001, H-2000.

Which electric strike can be used on fire rated pairs of doors ?

Murray — Thu, 04 Dec 2014 13:58:42 +0000

Periodically, we run into an application of FIRE RATED wood or hollow metal doors where a mortise lock is installed in the ACTIVE leaf of the pair and an electric strike is specified for the INACTIVE leaf. Although this is not a popular application, it is specified. Often in the field this application is filled by any electric strike that will fit in the door, however there are only a handful of electric strikes on the market that are approved for use in this application. In this case, ASSA ABLOY offers two electric strikes to accommodate this situation. The HES 1006 and FOLGER ADAM 742-72 strikes are listed with UL/cUL as approved for fire rated pairs.

This is a general UL approval but it is incumbent on the hardware specification writer and supplier to ensure the local codes are met and approved by the Authority Having Jurisdiction (AHJ)

How to Properly Install a Schlage cylinder into Yale Exit Hardware

Murray — Mon, 17 Nov 2014 14:24:58 +0000

Sometime’s life in the field isn’t as perfect as we would like it to be, there are occasions when you have to integrate other manufactures hardware into your own. One of the most common of these situations is keeping an existing or legacy key system during a complete hardware upgrade. Yale has you covered in this situation with a special manufactured housing to allow a Schlage rim cylinder into their 633F exit device trim. This custom housing allows for cylinder operation as if it were original Yale.

We hope you will find this to be a useful tip when dealing with these keying situations. Thanks for visiting our blog!!!!

How Rixson takes care of narrow leaves in uneven pairs

Murray — Mon, 03 Nov 2014 13:15:53 +0000

Mechanical rooms or storage areas in large buildings often have wider doors that need to be opened to move equipment in and out. Rather than have one door 5’ wide, there will be an UNEVEN pair. The active leaf generally is wider, say for instance 3’-6” while the inactive leaf may be 1’-6”.

To make the 1’-6” leaf inactive, there generally will be a flush bolt, surface bolt or roller catch of some descript at the lock edge of the door. When large items must be moved through the opening, the narrow door uses an overhead holder to aid in keeping the opening clear.

This can be a challenge for the overhead holder!

The added bolts on the door take up precious real estate on the smaller door. For instance, a door 18” wide may lose 5” for a roller latch. Now the door is technically 13” wide. Whether the Checkmate® is surface or concealed mounted, is not relevant. Thru bolts from surface units can be in conflict with the locking mechanism, almost as much as a channel cutout for a concealed unit.

When you are asked to supply the OH stop or holder for a door like this, it is extremely advisable to obtain ALL of the templates for the other hardware going into the opening. If the bolting hardware is NOT at a fixed position from the edge of the door, find out how far from the edge of the door it will be placed.

Very often, the extra hardware means special length tracks and arms for the OH stops or holders. Always advise your client that the product will have special pricing and templates BEFORE the drawings are made.

We hope you will find this to be a useful tip when dealing with openings of this nature. Thanks for visiting our blog!!!!
