Aligarh has been known as India's lock city for well over a century, and Tirupati Associates continues that tradition as a door lock and latch manufacturer supplying builders, hardware dealers and importers. This guide explains the difference between mortise locks and tubular latches, the sizes available and how to choose the right door lock for your project.
What Is a Mortise Lock?
A mortise lock is fitted into a pocket (mortise) cut into the edge of the door, so the lock body is hidden inside the door leaf. This gives a clean appearance and a strong, secure installation. Tirupati Associates manufactures mild steel mortise locks with 70 mm and 65 mm bodies, featuring precisely engineered latch and deadbolt mechanisms, matched strike plates and keys. Finishes include CP, BP, ZP and satin.
Where Mortise Locks Are Used
Mortise locks are the standard choice for main entrance doors, bedroom doors, offices, hotel rooms, hospitals and institutional buildings. Their robust internal construction handles daily locking for years, and they pair with our lever handles on plate for a complete, co-ordinated door set.
What Is a Tubular Latch?
A tubular latch is a compact latching mechanism fitted through a drilled hole in the door edge. It holds the door closed and is operated by a lever or knob handle. Tirupati Associates produces MS tubular latches in 65 and 75 mm backsets, including a heavy-duty bolt-through tubular latch that fixes through the door for extra strength on high-traffic doors.
Mortise Lock vs Tubular Latch
Choose a mortise lock when the door needs to be locked with a key and you want maximum security. Choose a tubular latch for internal doors that only need to stay closed, such as passage doors, living rooms and office interiors. Many projects use both — mortise locks on entry doors and tubular latches on internal doors — in matching finishes from Tirupati Associates.
Finishes for Every Interior
Our tubular latches come in ZP, BP, CP, MB, CuP, An.BP, Ch.St and Ni.St finishes, with options such as black or brass forends to match dark or gold-tone door hardware. This makes it easy to match locks with hinges, handles and bolts across a whole building.
