*****Since 1921, Master Lock Company has been providing padlocks and other security
products for the construction industry. Products include built-in combination and keyoperated locks for all types of lockers, combination padlocks for padlock hasp lockers,

plastic, and other types of locker:

1630MD, 1631MD, 1636MKADA, 1637MKADA, 1636MKMDADA, and

The specifier will need to select appropriate products and delete non-applicable models
and options. Refer to Master Lock product literature for descriptions and available
options. The guide section has been written so that most editing can be accomplished by
deleting unnecessary requirements and options. Depending on project requirements,
some additional information will need to be added by the specifier. Options are indicated
by [ ]. Notes to assist the specifier in selecting options and editing the specification
guide are printed in bold and indicated with *****. For final editing, all brackets and
notes will need to be deleted from the guide.
For ADA accessible locks, lock operation must meet the requirements of the current
edition of the Department of Justice (DOJ) ADA Standards for Accessible Design (ADA
Standards) or ICC/ANSI A117.1 – Accessible and Usable Buildings and Facilities.
Verify with local jurisdiction which standard has been adopted for the project location.

ADA Standards for Accessible Design; per Chapter 2, Article 2.25 – Storage; requires
providing a minimum of 5 percent ADA Accessible lockers (minimum of 1)
Master Lock recommends only ordering ADA compliant lock models to meet the
minimum 5 percent ADA requirement, with the remainder of the locks being ordered as
the standard models. For example, for a facility using lift handle lockers, a minimum of
5 percent of the locks should be model 1636MKADA and the remaining locks (typically
95%) should be specified as model 1630 locks. ADA locks are slightly more expensive, this
recommendation will provide the least cost option to meet the ADA Standards cited
above.
