Cantilever Slide Gate Theory:
The term, cantilever slide gate, may refer to any number of gates, from ornamental picket styles to functional chain link styles, from those that require cantilever rollers to those requiring gate tracks and trolleys. All cantilever slide gates will share certain characteristics which differentiate themselves from other types of slide gates. Steel Cantilever slide gates are unique from other types of slide gates in their construction, hardware choices, and design.
Cantilever slide gates are built larger than the gate opening they are designed to close, often as much as 50% larger than their respective openings. The idea here is to hang the gate on two or more mounting posts and have the gate suspend off these mounting posts into the gate opening to close. In general, no part of the gate comes in contact with the ground directly, or indirectly with any type of wheel. Instead, these slide gates 'cantilever' to close the opening. Cantilever construction allows for overhanging structures without external bracing. It is key that cantilever gate frame be constructed properly to help withstand the forces of gravity and wind. Intricate diagonal bracing and trusses are usually strategically welded in place to help prevent gate sag.
Advantages to cantilever slide gates over other styles are numerous. Since no part of the gate comes in contact directly or indirectly with the ground, cantilever slide gates are easy to automate with gate operators. Gates can often very easily be installed perfectly level. Proper design, fabrication, and installation of a cantilever slide gate will reduce friction during operation and prolong the life of a gate operator. Gate hardware systems from a quality fence supply source will provide smooth operation and low maintenance. A cantilever slide gate features the ability to slide along the fence line without requiring any lateral space as swing type gates demand.

Cantilever gate frames consist of 2-1/2" O.D. horizontal rails, 2" O.D. vertical bracing, and 1-5/8" diagonal bracing; all are welded and galvanized for the longest lasting gate. Chain link is 9ga. 2" mesh (1.2 oz. zinc galvanized after weaving). Gates are fully stretched, including counterbalance so they do not require modification if you wish to automate in the future.
The slide gate counterbalance should be approximately 1/2 the length of the gate opening. Minimum counter balance should be 4' long. If an automatic operator is to be installed, the counter balance may need to be longer so the operator can 'pull' the gate shut by the rear of the counter balance.
Post sizes are important. Generally steel chain link cantilever slide gates require 3" O.D. roller posts for widths up to 10' opening size. Use 4" O.D. posts up to 20' and 6-5/8" O.D. posts up to 32'. These specifications are for 6' high gates and shorter. For taller gates increase post sizes at each step and use 8-5/8" O.D. posts for 32' gates. We use mostly 4" OD steel posts for our aluminum slide gates.
Concrete footers need to be significant. 18" diameter x 42" deep is recommended for 3-4" posts, 24" diameter x 42" for 6-5/8" O.D. posts and 30" diameter x 48" for 8-5/8" O.D. posts. Increase bottom diameters 6"; creating a bell-shaped hole. The up and down stress with these type gates will 'work' even the largest posts out of the ground. Poor soil conditions, such as sand, will require larger footers. Always consult local building codes or practices prior to beginning any construction project. Call 811 prior to excavating post hole footers.
Yes, however the top and bottom rails of the gate can not be obstructed. The galvanized tubular top and bottom rail would be exposed so it is a matter of if how it would look. There isn't much point in painting these rails as it would rub off because of the rollers. The prices would not change even though we would not ship the gate with chain link. To attach wood to a cantilever gate, you may mount wooden 2 x 4s to the gate verticals and mount your pickets to the 2 x 4. This not only makes it easier to mount the pickets since you can now do so with regular nail, but it will also offset the fence and not obstruct the cantilever rollers. The frame could be hidden completely behind the wood or vinyl fence.
Use caution when trying to do this as there will be a large windload on all of the components once you sheet the gate in wood or vinyl. You will also be increasing the weight by 50%, possibly even doubling it. For this reason, you will likely need larger posts, and maybe even another set of roller posts. Hoover Fence is not responsible for this type of installation as our gates are not designed with this application in mind.
Customer Photo's of Western Red Cedar Installed on HFC Cantilever:
Generally, posts are set one day and allowed to cure in concrete. Gates typically deliver fully assembled and simply need hung from trucks or rollers. Installing posts and truck brackets plumb and level assures smooth gate operation. Exceptionally large gates may need shipped in more than one piece and assembly finished in the field. Two piece gates will be 'sleeved' for ease of assembly in the field.

It was a pleasure doing business with Hoover.
The product was excellent. The delivery was a little long on the gate. But I think itÂ’s just the COVID delays.
Excellent Company
Orders was sent back, not all parts came in and when I sent the length of the fence and the type gates I wanted they forgot to put the rollers on there, also left off the bolts and top eye caps. So now the customer has already paid for the product so these will be out of my pocket. Probably won't use again. Sorry
