A heavy duty slide bolt lock adds a simple mechanical barrier to a gate, shed, barn door, or interior door. The Alise 10-inch bolt is best for buyers who want a larger stainless steel latch; the YI LAI 6.3-inch models suit compact installations, while the 6.7-inch version offers a middle-size option. MeBantoo is a useful choice for shoppers seeking a black finish and included screws. Compare bolt length, diameter, mounting space, and padlock-hole size before choosing.

Alise 10-Inch Heavy Duty Barrel Bolt
Best for: Buyers who need a longer, substantial slide bolt for a barn door, fence, or gate. Its 10-inch overall length and 0.62-inch solid steel bar make it the largest listed option by length and bolt diameter.
The latch is made from SUS304 stainless steel and has a built-in padlock hole. A padlock is not included, so choose one separately if you want to secure the bolt against casual opening. The product listing describes it for indoor and outdoor uses, including gates, fences, and sheds.
Why it stands out: Its larger dimensions make it a better fit when a shorter latch may not provide the reach or presence required. Check first: Confirm the available mounting space and bolt alignment; its 10-inch length may be too large for a narrow door frame.
YI LAI 6.3-Inch Silver Slide Bolt
Best for: People who want a shorter latch with a relatively thick bolt. This model measures 6.3 inches overall and has a 14 mm (0.55-inch) solid bolt, with a padlock hole measuring 8 mm (0.32 inch).
Its SUS304 stainless steel construction is described as suitable for indoor or outdoor use. The center-positioning design allows left- or right-facing operation, and the latch can be installed horizontally or vertically. Installation requires drilling holes and fastening the lock with screws.
Why it stands out: It combines compact overall length with the largest stated bolt diameter among the listed 6.3-inch models. Check first: The listing calls for drilling during installation, and a padlock is not stated as included.
YI LAI 6.7-Inch Stainless Steel Bolt
Best for: Buyers who want a bolt longer than the 6.3-inch choices without moving to a 10-inch latch. It measures 6.7 inches overall and uses a 12 mm solid bolt.
The SUS304 stainless steel construction is listed for interior and exterior applications. Its padlock hole provides an option to add a separate padlock. The center-positioning design supports left- or right-facing use and horizontal or vertical installation, with holes drilled before the latch is screwed into place.
Why it stands out: It offers a useful middle ground in overall length and flexible installation orientation. Check first: Its bolt is narrower than the 14 mm bolt on the 6.3-inch YI LAI models, so compare diameter as well as length.
MeBantoo 6.3-Inch Black Slide Bolt
Best for: Shoppers who want a black-finish latch and included mounting screws. The 6-5/16-inch body has a 14 mm (9/16-inch) solid bar, and the package includes 10 stainless steel screws.
The latch is described as 304 stainless steel with a black finish. Its 9 mm (3/8-inch) padlock hole can accept a separate padlock. The product listing says it can be mounted on either side and in a horizontal or vertical direction. It also mentions a dust canister for bottom-ground installation.
Why it stands out: It combines a black appearance, a 14 mm bolt, and included screws. Check first: A padlock is not included, and the listing’s dimensions should be checked against the mounting surface before installation.
YI LAI 6.3-Inch Black Barrel Bolt
Best for: Buyers who prefer a black latch but want the YI LAI 6.3-inch design. Its listed dimensions and core features match the silver version: 6.3 inches long, a 14 mm solid bolt, and an 8 mm padlock hole.
The SUS304 stainless steel latch is described as suitable for indoor and outdoor use. The center-positioning design permits left- or right-facing operation and horizontal or vertical placement. Installation requires drilling and fastening with screws.
Why it stands out: Choose this if the black finish better suits the door or gate. Check first: Confirm that the 8 mm padlock hole fits the lock you plan to use; a padlock is not listed as included.
Buying Guide: How To Choose A Heavy Duty Slide Bolt Lock
What bolt length and diameter do you need?
Measure the mounting area and the distance the bolt must travel into its keeper. The listed options range from 6.3 to 10 inches overall. Bolt diameter also matters: the 14 mm models have a thicker stated bar than the 12 mm YI LAI 6.7-inch option. Do not select by overall length alone; check the product dimensions against the door, frame, and keeper position.
Will the latch be used indoors or outdoors?
All five listings describe stainless steel construction, and several identify SUS304 or 304 stainless steel. The Alise and YI LAI listings describe indoor and outdoor uses. MeBantoo specifies a black finish. Match the finish and stated material to the installation, while recognizing that product descriptions do not establish how a latch will perform in every environment.
Do you need a padlock?
A padlock hole lets you add a separate lock, but it does not mean a padlock comes with the latch. Compare the hole diameter with the shackle size of your intended padlock. The stated openings range from 8 mm on the YI LAI models to 9 mm on MeBantoo.
How will you mount the bolt?
Check whether horizontal or vertical placement suits your door and whether the bolt will align with the keeper. The YI LAI and MeBantoo listings describe multiple mounting orientations. The listed products may require drilling; MeBantoo specifically includes 10 screws. Verify the mounting surface and hardware requirements before starting.
