Premium Door Tower Bolt

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.

Key Features

Stainless Steel Construction: Resists rust, tarnishing, and corrosion in humid bathroom, kitchen, and outdoor gate environments ? a significant long-term advantage over mild steel or zinc-plated alternatives.

Four Size Options (4″ to 10″): Covers the full range from compact bathroom window latches to large main gate security bolts ? select based on door size, security requirement, and aesthetic proportion.

Medium and Heavy Duty Grades: Medium suits lighter interior and bathroom doors; Heavy Duty provides a thicker bolt and stronger staples for main entrance doors, external gates, and high-security applications.

Surface-Mount Installation: Screws directly onto the door face ? no mortising or cutting required, making it the simplest latch fitting to install or replace without carpentry tools.

Single-Hand Operation: Smooth sliding bolt mechanism operates easily with one hand for convenience in everyday use ? bathroom and bedroom bolts are operated frequently throughout the day.

Installation Guidelines

Step-by-Step Installation

Mark the bolt position on the door face ? typically at a comfortable hand height, near the door edge and aligned with the frame.
Position the bolt body on the door face and mark the screw holes with a pencil.
Drill pilot holes at the marked positions to prevent the wood from splitting when driving screws.
Screw the bolt body firmly to the door face using the provided or compatible stainless steel screws.
Slide the bolt to the extended position and mark the keep (receiver) position on the door frame or wall.
Fix the keep in the marked position, ensuring the bolt slides smoothly and engages fully without binding.
Test the bolt operation several times to confirm smooth sliding and secure engagement ? adjust keep position slightly if the bolt binds or does not engage fully.

Recommended Applications

Main Entrance Doors: 8?10-inch Heavy Duty bolt adds a secondary inside-face security bar on main doors, supplementing the door lock for night-time security.

External Gates & Compound Doors: 8?10-inch Heavy Duty for wooden or metal compound gates ? stainless steel handles outdoor exposure to rain and humidity without degrading.

Windows & Ventilators: 4-inch Medium Duty to latch window shutters in place when open or closed ? prevents wind from forcing shutters open unexpectedly.
