In the world of ironmongery, the “Architectural” designation represents a higher tier of mechanical performance. The 200mm Barrel Bolt is manufactured from Grade 304 Stainless Steel (SS304), ensuring it is naturally rust-proof and corrosion-resistant. This makes it equally suitable for luxury interior suites, high-traffic commercial plant rooms, or external perimeter gates in coastal environments.

Featuring a solid, oversized shoot, this 200mm Barrel Bolt provides excellent structural stability. 200mm Barrel Bolt length is ideal for mid-sized applications where a 100mm bolt feels too slight, but a 450mm bolt is unnecessary. Finished in premium Satin Stainless Steel (SSS), it offers a modern, brushed appearance that resists fingerprints and maintains its “showroom” finish even with frequent daily use.

Why the 200mm Barrel Bolt is the Professional Choice

Substantial 200mm (8″) Profile: Offers a robust presence on the door, providing more fixing points and better leverage than smaller standard bolts.
Heavy-Duty Solid Shoot: Constructed with a thickened diameter bolt to provide high shear resistance against forced entry or heavy wind loads on gates.
Grade 304 Stainless Steel Construction: Naturally resistant to oxidation and pollutants, ensuring the mechanism won’t seize or “pit” over time.
Precision Glide Internal Guides: Machined to tight tolerances to ensure the bolt slides smoothly and stays “snug” without the rattling common in pressed-steel alternatives.
Ergonomic T-Bar Knob: The oversized knob is designed for a comfortable, high-torque grip, allowing for effortless operation.
Universal Strike Plates: Supplied with both a flat plate for timber frames and a recessed socket for floor or masonry applications.

Professional Installation and Maintenance Tips

To ensure your 200mm Barrel Bolt provides a lifetime of security, follow these essential installation steps:

Marking the Throw: Extend the bolt fully into the “locked” position against the frame before marking your holes. Ensure there is 1mm of clearance at the back of the strike plate to prevent the bolt from “binding” due to seasonal door swelling.
Pilot Holes for Longevity: Stainless steel screws are incredibly tough but can be brittle when driven into hardwoods like Oak or Teak. Always drill a pilot hole 70% of the screw’s diameter to prevent the heads from snapping.
Strike Plate Recessing: For a truly “architectural” look, use a sharp chisel to recess the strike plate flush into the door frame. This not only looks professional but prevents the plate from being easily pried off.
Vertical Gravity Check: If installing the bolt vertically (at the top of a door), ensure the friction guides are tight enough to prevent the bolt from sliding down under its own weight when unlocked.
Dry Lubrication Routine: Avoid using sticky oils or WD-40, which attract dust. A quick puff of graphite powder or dry PTFE spray into the barrel once a year will maintain a “silk-smooth” architectural action.
