Everything You Need To Know, How to Identify A Hoppe Multipoint Lock Gearbox and where to get one.

Hoppe Lock Gearbox Identification and everything you need to know how to identify your current Hoppe lock, and measure it properly to get a replacement.
1. What Lock Series do you need? If it is Handle OVER European profile lock cylinder, Then it is a Hoppe HLS-9000 series. This is the most common lock used by Weather Shield, Older Peachtree doors, Kolbe and Kolbe, Therma-Tru doors, Fleetwood Doors, Older Hurd doors and several other door manufacturers. If it is Handle UNDER American lock cylinder, Then that is the HLS-7 series, which it is not as common as the Handle over Thumb turn version, HLS-9000 series.
2. What is the backset? This is the measurement from the edge of the door to the center of the handle post. This is pretty simple to measure since Hoppe only offers (4) different backsets. The options are 35mm (1 3/8"), 45mm (1 3/4" The Most Common Backset), 60mm (2 3/8"), and 70mm (2 3/4"). This is the first measurement to determine your lock gearbox.
3. What is the measurement from the center of the handle to the center of the thumb turn? This can be measured from the center of the handle to the center of the key hole from the exterior, or the center of the handle to the center of the thumb turn knob on the interior of the door? This one is easy. 92mm (3 5/8") is the common "PZ" measurement on all Hoppe lock series available. This is the second measurement to determine your replacement lock gearbox.
4. What is the deadbolt throw measurement? This is another easy one, since there are only (2) deadbolt throw sizes that are offered by Hoppe. 14mm (1/2") and 25mm (1" Most common size) This is the final measurement in the product part number to identify your Hoppe gearbox replacement.
Below are the Hoppe gearbox part numbers and an explanation of the part numbers. Example:
(35mm ) 1 3/8" Backsets:
IWP-35-92-14
35mm (1 3/8" Backset) - 92mm (3 5/8" PZ) - 14mm (1/2" Deadbolt throw)
IWP-35-92-25
35mm (1 3/8" Backset) - 92mm (3 5/8" PZ) - 14mm (1" Deadbolt throw)
(45mm ) 1 3/4" Backsets (The Most Common in USA)
IWP-45-92-14 (used mainly on single doors)
45mm (1 3/4" Backset) - 92mm (3 5/8" PZ) - 14mm (1/2" Deadbolt throw)
IWP-45-92-25 (Most common Hoppe Lock Gearbox replacement size)
45mm (1 3/4" Backset) - 92mm (3 5/8" PZ) - 14mm (1" Deadbolt throw)
Note: On 60mm and 70mm backsets, Hoppe only offers 1" (25mm deadbolt throws) on this lock configuration. So, That makes it ever more simpler to Identify a replacement gearbox. All you really need is the backset measurement since the Handle to Thumb turn knob "PZ" will always be 92mm (3 5/8" and the deadbolt throw will always be 25mm (1").
(60mm ) 2 3/8" Backsets (Not Very Common)
IWP-60-92-25 (Available, But not a stock item)
60mm (2 3/8" Backset) - 92mm (3 5/8" PZ) - 25mm (1" Deadbolt throw)
(70mm ) 2 3/4" Backsets (Not Very Common)
IWP-60-92-25 (Available, But not a stock item)
70mm (2 3/4" Backset) - 92mm (3 5/8" PZ) - 25mm (1" Deadbolt throw)
The IWP-45-92-25 gearbox is the most commonly used to replace 95% of the locks that we encounter, Every once in a while we will get an oddball size that will take a few weeks to arrive once we have ordered it.
I hope this simple video and the verbal explanation will help you find the Hoppe lock gearbox and make it easier to understand how the lock is identified. Have a wonderful day!!!!!!! Ralph
