HIPAD glass door hardware: floor springs, door closers, patch fittings and pivots

What Is Glass Door Hardware?

A frameless glass door is a single sheet of tempered glass with no frame. Because the glass cannot be screwed into, every fitting clamps onto it. The most common commercial set uses a floor spring set in the floor under the door: a bottom patch fitting on the lower corner of the glass sits on the floor spring spindle, and a top patch fitting turns on a top pivot in the transom or ceiling. A pull handle goes through holes in the glass, and a lock patch or floor lock secures the door.

Where the floor cannot be cut, a door closer or a concealed frameless closer does the closing instead. The same hardware is used on shop fronts, office entrances, hotel lobbies, glass partitions and bathroom doors. In Spanish the floor spring is a bisagra hidráulica de piso of freno hidráulico, patch fittings are zapatas of herrajes para puerta de vidrio templado, and the door closer is a cierrapuertas.

Step 1 · How the door closes

Floor Spring vs Door Closer vs Pivot vs Concealed Glass Door Closer

Kort antwoord: use a floor spring for heavy, busy frameless glass entrances where the floor can be cut; a surface door closer for framed, timber and steel doors; a pivot system for oversized or architectural doors; and a concealed frameless glass door closer when the floor cannot be cut and the glass door is up to 100 kg.

	Floor spring	Door closer	Pivot system	Concealed glass door closer
Where it sits	In a pocket in the floor	On the door face or frame head	Floor and head pivots	Inside the bottom patch, no floor pocket

Het meest geschikt voor	Shop fronts, malls, office entrances	Interior, fire and service doors	Feature entrances, villas	Renovations, bathrooms, offices

Step 2 · Floor spring size

How to Choose a Floor Spring by Door Weight and Size

Choose a floor spring whose maximum door weight en maximum leaf size both cover your door. Tempered glass weighs about 2,5 kg per m² per millimeter: a 1000 × 2400 mm door in 12 mm glass weighs about 72 kg before fittings, so a 100–120 kg floor spring leaves a safe margin.

All HIPAD floor springs have two-stage speed control: one valve for the closing swing, one for the final latching.
They suit single and double doors in glass, timber and uPVC.
Check the floor depth: floor spring boxes are about 42–70 mm deep.

HIPAD floor spring range: 12 models. Each model's exact ratings and box size are on its drawing.
Max door weight	Max door leaf (W × H)	Typische toepassing
75 kg	750 × 2100 mm	Light interior glass doors
95–100 kg	950–1000 × 2100–2200 mm	Office and bathroom glass doors
120–135 kg	1100–1200 × 2200–2500 mm	Shop fronts, hotel doors
150 kg	1200 × 2300–2400 mm	Busy commercial entrances
180–200 kg	1500 × 2200–2500 mm	Large entrance doors
250 kg	1500 × 2600 mm	Oversized and heavy doors

Step 3 · Door closer size

How to Choose a Door Closer

Door closers are sized by door weight and width. HIPAD surface closers cover doors from 25 to 110 kg in square, round and triangular bodies, and concealed closers cover 35–95 kg doors. Most models are available with or without 90° hold-open.

Finishes: brushed, titanium, red bronze, green bronze and black.
Door weight	Typical door width	HIPAD closer type
25–45 kg	Up to about 1000 mm	Compact square or round closer
45–65 kg	Up to about 1200 mm	Standard square or round closer
60–80 kg	Up to about 1300 mm	Large square or round closer
80–110 kg	Up to about 1000 × 2000 mm leaves	Heavy-duty triangular closer
35–95 kg	Up to about 1300 mm	Concealed closer

EN 1154 closer sizes (reference)

Many specifications in Europe and the Middle East call for closers by EN 1154 power size. Match the HIPAD model to the size the specification asks for.

EN size	Max door width	Door weight
EN 2	850 mm	Up to 40 kg
EN 3	950 mm	Tot 60 kg
EN 4	1100 mm	Tot 80 kg
EN 5	1250 mm	Up to 100 kg
EN 6	1400 mm	Tot 120 kg

No floor cut

For renovations, offices and bathrooms where the floor cannot be opened, HIPAD supplies a frameless glass door closer built into the bottom fitting. It needs no floor pocket and no embedding work.

Door weight	Up to 100 kg
Door width	Up to 1000 mm
Glas	8–13 mm tempered
Opening	150° each way; 90° hold-open optional
Speed	Closing zone 150°–10°, latching zone 10°–0°

Installatie	No floor recess, no embedding

Fix the glass

Patch-aansluitingen

Patch fittings clamp the corners of a frameless glass door and connect it to the floor spring and top pivot. A standard top or bottom patch measures about 164 × 51 × 32 mm.

Patch	Job
Bottom patch	Sits on the floor spring spindle
Top patch	Turns on the top pivot
L-corner patch	Joins a fixed sidelight and fanlight at the corner
Lock patch	Holds a floor lock or keeps for double doors

Spindle inserts are available for 15 mm and 11.8 mm floor spring spindles, which covers the most common floor springs on the market. Tell us which floor spring the door uses.

Glass Door Hardware FAQ

What hardware is needed for a frameless glass door?

A frameless glass door on a floor spring needs a floor spring, a bottom patch fitting, a top patch fitting with a top pivot, a pull handle and a lock patch, floor lock or center lock. Double doors need a set for each leaf and usually a center lock.

What is the difference between a floor spring and a door closer?

A floor spring is set into the floor under the door and carries its weight, so it suits heavy frameless glass doors and is almost invisible. A door closer is fixed on the door or frame head and only closes the door, so it suits framed, timber and steel doors.

How do I choose a floor spring size?

Choose a floor spring whose maximum door weight and maximum leaf size both cover your door. HIPAD floor springs range from 75 kg for 750 × 2100 mm doors to 250 kg for 1500 × 2600 mm doors.

Can a glass door close automatically without cutting the floor?

Yes. A concealed frameless glass door closer sits inside the bottom fitting and needs no floor pocket. HIPAD's model carries doors up to 100 kg and 1000 mm wide in 8–13 mm glass, opening 150° each way.

What glass thickness is used for glass doors?

Commercial frameless glass doors normally use 10–12 mm tempered glass, with 12 mm common for busy entrances. All holes and notches must be cut before the glass is tempered.

What sizes do your glass door pull handles come in?

Back-to-back glass pull handles come in 300–1200 mm lengths for 8–12 mm glass in SUS304 or SUS201. Heavy-duty entrance pulls come in 600–1500 mm for 35–70 mm doors, and long pulls with locks up to 1850 mm.

Do your patch fittings fit our floor springs?

HIPAD patch fittings are available with spindle inserts for 15 mm and 11.8 mm floor spring spindles, which covers the most common floor springs. Tell us the floor spring model and we will confirm the insert.

Can you supply a complete glass door hardware set?

Yes. We supply floor springs, patch fittings, pivots, handles, locks and flush bolts in one finish, packed per door for projects or in bulk for distributors, with logo and private-label packing available.

Is HIPAD een fabrikant of een handelsonderneming?
