Delivered when we needed it

This event truly is happening because of your team's effort. Without it, we wouldn’t have been able to open a whole new section of the venue and would have had to stop ticket sales much earlier. Thanks for the terrific work. Please pass along my appreciation to everyone on the Bridge Brothers and Topper team. The really great thing is, not only does the bridge look great, but it was delivered when we needed it! I wanted to let you know that 110 million people around the world will also see it during the race. Let's do more together in the future.

Gangway and Dock Security Gates

Designed to Fit Your Aesthetic

Topper security gates can be simple and utilitarian or complex and architecturally exotic. Gates are typically designed with vertical picket infill, glass or perforated metal. Many security gate installations have extended wing panels to enhance security.

Door hinges are critical to every gate design. With many years of experience Topper has developed the finest hinge available, ensuring long, trouble free, repeated use of the gate. Door closers are commercial grade and suitable for the outdoor marine environment. We provide the door hardware, including door pulls, latches, keyed locks, push button locks or card reader access.

To assure a consistent visual appearance to your facility, Topper can also provide associated railing and security fencing.
