Product Description

Premium Door Tower Bolt is a surface-mounted sliding bolt used to secure doors, gates, and windows from the inside — the most common door security fitting in Indian residential and commercial construction. Available in 4-inch, 6-inch, 8-inch, and 10-inch lengths and in Medium and Heavy Duty strength grades, the range covers every application from lightweight interior bathroom latches to heavy gate bolts and main door security bars. All variants are manufactured from stainless steel for corrosion resistance — resisting the rust, tarnishing, and surface degradation that affect mild steel and zinc-plated tower bolts in humid bathroom, kitchen, and outdoor gate environments within a few years of installation.

Tower bolts work by sliding a cylindrical or rectangular bolt barrel horizontally or vertically through a pair of staples mounted on the door face, engaging with a keep (receiver) fixed to the door frame or wall — no key is required, and the bolt can be operated with one hand. The Medium Duty variant suits lighter interior doors, bathroom doors, bedroom doors, and windows where the bolt sees moderate daily use; the Heavy Duty variant provides a thicker bolt barrel and more robust staples for main entrance doors, external gates, and large wooden or metal doors where greater security load and frequency of use demand a stronger fitting. Size selection follows the door width and the desired engagement length — longer bolts engage more deeply into the keep for higher security, and are also more visible as a design element on larger door faces.

FAQs

1) What is the difference between Medium Duty and Heavy Duty — which should I choose?

The difference is in bolt barrel diameter, plate thickness, and staple strength. Medium Duty is sized for lighter interior doors — bathroom doors, bedroom doors, and interior panel doors — where the bolt is used for privacy rather than security and sees standard daily use. Heavy Duty has a thicker, more robust bolt and stronger staples for main entrance doors, compound gates, and external doors where higher security load, greater frequency of use, and resistance to forced entry are requirements. When fitting a tower bolt as a secondary security bar on a main door, always use the Heavy Duty variant.

2) Which size should I choose for my door?

Use 4-inch for bathroom and toilet doors, windows, and small interior latching applications. Use 6-inch for bedroom doors and standard interior doors where a slightly longer bolt provides a more proportionate appearance on a full-height door. Use 8-inch for main entrance doors and larger interior doors where deeper bolt engagement and a more prominent security presence are desired. Use 10-inch for compound gates, large external doors, and applications where maximum bolt length and engagement depth are the priority.

3) Can tower bolts be used on metal gates and outdoor applications?

Yes — stainless steel tower bolts are suitable for outdoor gate and compound door applications where the fitting is exposed to rain, humidity, and temperature cycling. Stainless steel resists the rust and surface corrosion that causes mild steel and zinc-plated bolts to seize and fail in outdoor environments within 1–2 monsoon seasons. For outdoor use, use the Heavy Duty variant and fix with stainless steel screws to ensure the entire fitting is corrosion-resistant — using mild steel screws with stainless hardware creates a galvanic corrosion risk at the fixing points.

4) How is a tower bolt different from a door latch or lock — do I need both?

A tower bolt is a simple manual sliding bolt that secures a door from the inside only — it cannot be operated from outside and provides no key-based security. A door latch or mortise lock provides two-way operation (inside and outside) and key-based security. In Indian residential practice, tower bolts are used in addition to door locks — as inside-face privacy latches on bathroom and bedroom doors, and as secondary night-time security bolts on main entrance doors. They serve different functions and are typically installed together rather than as alternatives.

5) Do the bolts come with screws, and what type should I use for installation?

Confirm with the product packaging whether fixing screws are included. If sourcing separately, use stainless steel wood screws of appropriate length — typically No. 8 screws, 25–32mm for timber doors and frames. Using mild steel or zinc-plated screws with stainless steel tower bolts is not recommended — in humid bathroom and outdoor environments, dissimilar metals in contact can cause galvanic corrosion that degrades both the screw and the bolt plate around the fixing hole over time. Matching stainless screws ensure a fully corrosion-resistant installation.
