Tubular vs. Cylindrical Lockset: What’s the Difference and Which One is Right for You?

Choosing the right door lock is crucial for security, durability, and ease of use. Whether you're securing a home, office, or commercial space, understanding the differences between tubular and cylindrical locksets can help you make an informed decision.

Both lock types are common, but they serve different purposes. In this guide, we’ll break down their mechanisms, key differences, pros and cons, and best applications so you can determine which one suits your needs.

What is a Tubular Lock?

A tubular lock is a type of bored lockset, meaning it is installed into a hole drilled into the door. The latch mechanism is located in the edge bore, and the lock operates using a keyway shaped like a circle.

How Does a Tubular Lock Work?

• The key has grooves that fit into the lock’s circular keyway.
• Inside, seven or eight pins are arranged in a ring shape.
• When the correct key is inserted, the pins align, allowing the lock to open.
• The inside and outside spindles are connected, so they move together when turning the knob or lever.

Where Are Tubular Locks Used?

Tubular locks are common in light to medium-duty applications, including:

✔ Residential doors (interior bedroom or bathroom doors)

✔ Bike locks

✔ Vending machines

✔ ATMs

✔ Office furniture or cabinets

What is a Cylindrical Lock?

A cylindrical lock is another type of bored lockset, but it has a stronger, more complex mechanism. Instead of a simple latch assembly, the lock’s retraction mechanism is built into the chassis.

How Does a Cylindrical Lock Work?

• The lock consists of a knob or lever on both sides.
• The key aligns the internal pin tumbler mechanism, which then allows the latch bolt to retract.
• Unlike tubular locks, the inside and outside spindles operate independently, allowing for more security features.

Where Are Cylindrical Locks Used?

Cylindrical locks are widely used in commercial and high-traffic areas, including:

✔ Office buildings

✔ Schools and classrooms

✔ Hotel doors

✔ Hospitals and healthcare facilities

✔ Storerooms and utility rooms

Which Lock Should You Choose?

✅ Choose a Tubular Lock if:

You need a light-duty lock for residential interior doors (bedrooms, bathrooms, closets).

You want an affordable and decorative option.

You prefer an easy-to-install lock with basic security.

You need a lock for light-security applications (cabinets, office furniture, vending machines).

✅ Choose a Cylindrical Lock if:

You need a durable, high-security lock for commercial spaces (offices, schools, hospitals).

You require fire-rated locks for compliance and safety (emergency exits, hotel doors).

You want a lock that withstands heavy use in high-traffic areas.

You need advanced locking functions (storeroom, classroom, entry, passage).

You are securing an exterior door or main entrance.

Frequently Asked Questions (FAQ) About Tubular vs. Cylindrical Locks

1️⃣ Which lock is more secure: tubular or cylindrical?

🔹 Cylindrical locks offer higher security because they have independent spindles and stronger mechanisms, making them more resistant to forced entry. Tubular locks are secure for light-duty applications but are easier to pick or break compared to cylindrical locks.

2️⃣ Are tubular locks harder to pick?

🔹 Tubular locks are harder to pick than standard pin tumbler locks because they require a special tubular lock pick. However, they are still vulnerable to experienced locksmiths or lock-picking tools.

3️⃣ Which lock is better for commercial use?

🔹 Cylindrical locks are the better choice for commercial settings. They are durable, fire-rated, and support multiple locking functions (e.g., storeroom, classroom, and passage locks). Tubular locks are more suitable for residential or light-duty applications.

4️⃣ Can I install a tubular or cylindrical lock myself?

🔹 Tubular locks are easier to install with basic tools, while cylindrical locks require more precision and expertise. If you’re not experienced with lock installations, hiring a professional locksmith is recommended for cylindrical locks.

5️⃣ What is the price difference between tubular and cylindrical locks?

🔹 Tubular locks are generally cheaper due to their simpler design. Cylindrical locks cost more but offer better security and durability, making them a smart investment for high-traffic areas.

6️⃣ Can I use a tubular lock on an exterior door?

🔹 While you can use a tubular lock on an exterior door, it is not recommended for high-security needs. For front doors or commercial entrances, a cylindrical lock (or a deadbolt combination) is a much safer choice.

Final Thoughts: Which Lock Should You Choose?

Both tubular and cylindrical locks have their place depending on security needs, durability, and application. If you're looking for a decorative and easy-to-install lock for residential use, a tubular lock is a great choice. However, for high-traffic commercial buildings that require durability and advanced security, a cylindrical lock is the better option.
