How is a closer hinge different from a floor spring or overhead closer?
Floor springs handle very heavy glass doors, but they require cutting into the floor, which is costly and hard to add later. Overhead closers are easier to fit, but the arm or track is visible across clear glass. Closer hinges mount only at the hinge points, so there is no floor work and nothing across the top of the glass. They work on single-swing glass doors up to 260 lbs.
Can you self-close a glass door without a floor spring?
Yes. Waterson hydraulic closer hinges close the glass door from the hinge points, so you do not need a floor spring or an overhead closer. This makes them a practical choice for retrofits, rental spaces, and floors you cannot or do not want to cut.
How do I choose a closer for a frameless glass door?
Answer four questions:
- What is on the hinge side? Another glass panel, a wall, or a door frame. This decides the mounting type.
- How tall and heavy is the door? This decides how many hinges you need.
- How thick is the glass? Waterson glass closer hinges fit 5/16" to 1/2" glass.
- Does the door need to stay open sometimes? If yes, choose a hold-open (D) set.
Which mounting type do I need: glass-to-glass, glass-to-wall or glass-to-frame?
Look at what the door hangs from. Glass-to-glass hinges (K51GG) connect the door to a fixed glass panel, common in glass storefronts and office partitions. Glass-to-wall hinges (K51GWL) mount the door directly to a wall. Glass-to-frame hinges (K51GM) mount the door to a metal or wood frame, a common choice for commercial glass doors.
What glass thickness do closer hinges fit?
Waterson glass door closer hinges fit glass from 5/16" to 1/2" thick (8 to 12.7 mm). The hinge cutouts in the glass need to be made by your glass fabricator before the glass is tempered, following the Waterson template.
How heavy a glass door can a glass door closer handle?
It depends on the number of hinges. A 2-hinge set handles glass doors up to 6 ft tall and 150 lbs. A 3-hinge set handles doors up to 7 ft and 260 lbs. For tall glass doors up to 8 ft, use a 4-hinge set such as the K51GM-D4.
Can a glass door closer hold the door open?
Yes. D sets, such as the K51GG-600-D3 and K51GM-D3, hold the glass door open when you need it, which is useful for busy shop hours, deliveries or airflow. A light push releases the door, and it closes on its own. If you do not need hold-open, B sets like the K51GM-B3 close the door every time.
How do I adjust the closing speed of a glass door closer?
Each Waterson hinge has a numbered panel on the end, so you can see and set the closing force precisely.
- Raise the spring tension one number at a time until the door closes and latches on its own.
- Adjust swing speed first, then latch speed, using the hex wrenches in the box.
- Lock the settings with the 3 mm hex wrench, then fine-tune if the door slams or does not close fully.

Do glass door closer hinges work on exterior doors?
Yes, they are rated for interior and exterior use. However, they are designed for environments above 32°F (0°C). For exterior glass doors in places that drop below freezing, check with our team before ordering.
Do glass doors need a door stop with closer hinges?
Waterson glass closer hinges work with doors that open up to 120°. If your door can swing further, add a door stop to protect the hinges and the glass.
What finishes are available for glass door closers?
Satin stainless steel (US32D) and flat black (US19). Satin stainless suits most storefronts and offices, while flat black pairs well with black-framed glass and modern interiors.
Can glass door closer hinges be returned?
Glass door closer hinges are non-refundable. Because glass doors are made to size and the hinge cutouts must match exactly, please talk to our sales team to confirm the right set before you order.
