Security bars
Retractable security barriers that glide on their tracks, lock without a padlock, and look like they belong on the house.
It moves
The same doorway, three times. Older retractable bars stick and drag; these ride on self-lubricating bearings and stack flat against the frame when you are done.
We're here to make it simple and seamless with a system that's both tough on crime and built to last.
About security bars
Mulholland Brand is the USA's exclusive licensed manufacturer and installer of the Trellidor Ultimate Crime Barrier. Each retractable barrier is custom-made to fit your own doors and windows, glides on its track without binding, and locks with a patented Trellidor deadlock or slamlock, no padlocks. Galvanized steel, powder-coated, built to make life hard on a burglar and easy on you.
Warranties cover defective workmanship, materials and corrosion.
Why galvanised steel
Powder-coated galvanised steel is what lets a barrier take an attack, take the coast, and still slide with one hand years later.
An electrostatically applied powder-coat finish leaves the barrier bump and scratch resistant, water-tight and highly resistant to corrosion.
Powder-coated galvanized steel does not decay the way wood or iron does, and the alloy stands up to aggressive vandalism and forced-entry attempts.
Several trellis designs, and powder coating applied in production means a wide range of colors rather than a single industrial finish.
The trellis pattern sits comfortably on a period house or a modern one, so the barrier protects the property without arguing with it.
Patented upgrades make the system stable and easy to operate, needing little adjustment over time. Older retractable bars are a struggle to move and far likelier to cause an injury.
Powder coating is a dry process. Unlike solvent-based wet paint it releases no harmful solvents or airborne pollutants, which matters most to the people applying it.

For the home
Security Gates
If keeping your family safe means preserving your home's beauty and function, this is your ideal match. Our residential retractable security bars slide discreetly into place: strong when you need them, invisible when you don't.
Designed for effortless operation, they safeguard children and pets without impeding light, design, or your sense of home.
For business
Security Gates
For businesses, security must match its professional appearance. Our commercial retractable gates are engineered from powder-coated steel custom-fitted to your storefront or facility.
Designed to withstand tampering, rust, and daily use, Mulholland's Security Gates provide strong protection while maintaining curb appeal and smooth workflow.
Tested, not asserted
Trellidor puts these through a series of attack tests. The wrecking ball is one of them. Barriers are made from galvanised steel and powder-coated on top, and lock with a patented Trellidor deadlock or slamlock rather than a padlock anyone can cut.
Installations
Why Mulholland
The USA's only licensed Trellidor manufacturer, measuring and building every barrier for the opening it goes in rather than cutting a stock unit down to fit.
Powder-coated and corrosion resistant even on the coast, on self-lubricating bearings that keep the glide light for years rather than months.
High-end models are internationally certified for strength under attack, and every barrier locks without a padlock so nothing blocks an exit in a fire.
Local, family-run, and installed by our own crew: the same people who measured the opening are the ones who fit the barrier.
Financing available
