Very rugged and heavy. I thru bolted it and created an indestructible drop down door. I do need to rebalance the spring assist due to the extra weight.

You don’t realize exactly how heavy duty this hinge is till you’re holding it in your hands. Probably a bit overkill for my ramp door replacement but I know it’s the last hinge I’ll ever have to install.

I am using this as a vertical door hinge for my shed. It is working perfectly. The heavy shed door no longer sags. The hinge operates smoothly. It was probably overkill but I don't like having to fix things more than once.

See what our Experts say about this Marlboro Trailer Door Hinges
- Recommendations for a Transition Hinge for a Cargo Trailer RampThe best hinge we have for your application is the 6" Wide Continuous Hinge - 1/2" Pin Diameter - Steel # MA32VR (8' long) or the # MA52VR (6' long). Since both of these hinges measure 6 inches wide, they give you plenty of space to weld on or bolt on to your trailer ramp. They also rotate a full 270 degrees for a full opening/closing range.
view full answer... - Weight Capacity Of Marlboro Continuous Piano HingeHinges like the 6" Wide Continuous Hinge - 6' Long - 1/2" Pin Diameter - Steel # MA52VR do not have weight capacity ratings and it is up to the installer to determine if it will be strong enough. We do have a longer 8 foot long variant, the 6" Wide Continuous Hinge - 8' Long - 1/2" Pin Diameter - Steel # MA32VR.
view full answer... - Load Rating of Marlboro Continuous Piano HingeThe 6" Wide Continuous Hinge - 6' Long, # MA52VR is not provided from the manufacturer with a load rating. This for the fabricator to evaluate if this component meets needs of the intended application.
view full answer... - What 3" Wide, 6' Long Hinge Has a 3/16" Thick Side Plate? The side plates on the 3" Wide Continuous Hinge # MA65VR you found are 0.09" thick which is just under 3/32". We do have a 3" Wide # MA52VR which is 6' Long with a 1/2" pin that has 0.18" thick side plates which is slightly thicker than 3/16" thick.
view full answer... - Recommendation For Removing Surface Rust on Steel Trailer Door Hinge And Preventing Returning RustOn a Steel Hinge # MA52VR you will want to use a wire brush to remove as much surface rust as possible. Then you will be able to coat the hinge with a rust preventative paint on the main surface area. On the actual hinge portion it is best to coat that area with a lubricant like WD-40 which helps to displace moisture and prevent rust.
view full answer... - Can The Marlboro Continuous Hinge Be Cut Down To Fit Different LengthsYes, the 6" Wide Continuous Hinge # MA52VR is able to be cut down. I recommend removing the pin and cutting each piece separately. When you place the pin back in you can use a hole punch to taper in the bottom pin holder just a bit so that it doesn't wiggle down with any road vibration.
view full answer... - What Lengths Are The Marlboro 6" Wide Continuous Hinge Available In? The 6" Wide Continuous Hinge we currently only carry in a 6' # MA52VR and 8' # MA32VR length. The 6' length is the shortest piano style hinge we carry for all the different width hinges. You can cut the hinge down to whatever length you need. You may need to peen over the hinge pin to prevent the pin from sliding out after you cut the hinge.
view full answer... - Is There A 4' Long x 6" Wide Continuous Hinge With A 1/2" Pin Size Available We do not currently carry a continuous hinge in a 4' length so you would need to get the 6" Wide Continuous Hinge - 6' Long - 1/2" Pin Diameter # MA52VR and cut it down to fit your needs.
