LATCHING/LOCKING
OPTIONS
These latches/locks are the third character in the
part code:
(Example: NWC2424) |
C
- Screwdriver operated cam latch.
This latch is the most common on access panels,
providing easy access in standard applications. |
 |
| L
- Key operated cylinder lock. When
locks are required, this lock provides an economical solution
for controlled access. |
 |
| M
- Mortise cylinder lock preparation. Offers
a higher level of security. These locks can be matched to the
project hardware. Nystrom's doors accept a standard 1-1/8"
mortise cylinder by most lock manufacturers (Best, Corbin, Russwin,
Schlage, etc.). |
 |
| N
- Knurled knob cam latch.
The knurled knob latch is finger operated, so it provides unrestricted
access for times when using a tool or key to open the panel
is not desired. |
 |
| H
- Hex head cam latch. This latch requires
a standard allen wrench to open the door, providing a higher
level of security than a screwdriver latch. |
 |
| P
- Pinned hex head cam latch.
For more secure applications, the pinned hex head cam latch
allows tamperproof access. The latch requires a special pinned
allen wrench to open the door. |
 |
| S
- Security screw - Pinned hex head.
Security screws allow the highest level of security without
a lock cylinder. A special pinned allen wrench is required to
open the door (sold separately). |
 |
| D
- Detention lock preparation. The
detention lock preparation will accommodate several brands of
heavy-duty detention deadbolt locks. The most common use for
this option is in maximum security applications. |

MATERIAL
OPTIONS
These options are added to the part code after the
size:
(Example: NWC2424B) |
| B
- Galvanized bonderized steel. This
material is an economical choice for use where a corrosion resistant
material is required. |
 |
| S
- Stainless steel type #304. With
#4 satin polish finish. Stainless steel material is typically
used in areas that require the highest level of corrosion resistance.
It is also used in areas where a polished stainless steel look
is desired. |
 |
| G
- Gasketing. Gasketing can be applied
to the doorstops of the frame to provide weather resistance
and reduce airflow between the door and frame. (A UL listed
smoke seal gasket is also available.) |
 |
| H
- Continuous piano hinge. Occasionally,
a flush piano style hinge is required on access panels for specification
compliance. |
 |
| L
- Louvered door. Some access door
styles can be manufactured with a louvered door to provide ventilation
in special applications. |
 |
| Z
- Concealed continuous piano hinge.
This hinge option provides added security while maintaining
an appealing appearance. |
 |
| N
- No hinge.
For special applications that require door to be completly removed
from frame. |
