Andersen Auxiliary Security Lock, Foot Latch
Best for: Andersen door owners seeking an OEM-style security latch. This white foot latch provides a 3-3/4 inch length and aligns with Andersen hardware aesthetics. The design integrates as a foot-operated latch that mounts along the door edge, delivering straightforward use when the door is closed. Consider this option if you prefer an original-brand fit and a simple installation.
Limitations: This product is designed for Andersen doors, so compatibility may be limited with non- Andersen brands. Confirm mounting hole placement before purchasing.
Prime-Line U 9869 Sliding Door Lock
Best for: Budget-conscious buyers needing a secondary locking mechanism for most sliding patio doors. This 5/16″ diameter foot-operated lock is designed to function as a ventilating or security lock, with 7/8″ x 1-3/4″ hole centers and a 7/16″ throw. It fits most sliding vinyl panels when mounted on the sliding panel door.
Limitations: Not a universal fit for every door system; installation requires drilling and alignment to hole centers. Check your door panel thickness and frame clearance before purchase.
Gliding Patio Door Foot Lock (1997301 Compatible)
Best for: Andersen gliding doors that require a dedicated foot bolt with precise mounting. This white diecast lock is designed for Andersen OEM Part #1997301 and centers mounting holes at 2-13/16″. It provides a clear, purpose-built installation path for maintaining security on gliding doors.
Limitations: Installation is not universal; use only with compatible Andersen models. Follow the included guide steps to ensure the rod sits correctly above the sill when retracted.
Gliding Patio Door Foot Lock (1997220 Compatible)
Best for: Andersen gliding doors requiring the 1997220 mounting pattern. Similar to the 1997301 variant, it centers at 2-13/16″ and is stone diecast, offering a visually coordinated look with many door designs.
Limitations: This model is specifically designed for Andersen systems. Ensure mounting hole compatibility before ordering, and follow installation steps to align the rod height with the sill.
HauSun Patio Sliding Door Foot Lock
Best for: Homeowners seeking two-position locking with versatile installation on top or bottom rails. The HauSun foot lock offers a strong entry resistance, and its two locking channels enable a closed or slightly opened breeze mode while maintaining security.
Limitations: Some installations may require careful alignment to ensure the door does not tilt or bind in the track. It is sold as a single-pack option, so consider quantity for larger installations or multi-door setups.
Buying Guide
- Compatibility: Confirm door brand and model compatibility before choosing a foot bolt. Some products are designed specifically for Andersen doors or require universal mounting.
- Mounting hole centers: Many locks specify mounting hole centers (e.g., 2-13/16″). Measure your door edge to ensure a proper fit.
- Locking position: Decide if you want a two-position lock (closed and slightly opened) or a single secure position. Two-position locks provide airflow while maintaining security.
- Material and finish: Diecast or metal bodies in white or stone finishes help with aesthetic integration and durability against weather.
- Installation requirements: Some models require simple drilling; others depend on OEM parts. Prepare tools like a drill, bits, and a level for precise alignment.
- Security level: Foot bolts add physical resistance but should complement, not replace, other door security features such as proper threading, weatherstripping, and door alignment.
- Installation ease vs. performance: Higher-cost, door-specific options may offer easier installation and more reliable alignment, though universal options cover broader applications.
FAQ
- What is a patio door foot bolt and how does it work?
A patio door foot bolt is a small locking mechanism mounted on the door edge that prevents the door from opening by engaging with the floor or sill when the bolt is extended.
- Can I use any foot bolt on any sliding door?
Not always. Some are designed for specific brands (such as Andersen) or door types. Check mounting hole centers and compatibility notes before purchasing.
- Is a two-position foot lock better than a single-position lock?
Two-position locks offer an option to allow ventilation while maintaining security, which can be advantageous in mild weather or when you want airflow without full opening.
- What installation tools are typically required?
Common tools include a drill with appropriate bits, a ruler or caliper for hole spacing, a screwdriver, and a level to ensure the bolt sits flush and perpendicular to the sill.
- Are foot bolts a substitute for a door reinforcement kit?
No. Foot bolts provide additional physical security, but they should be used in conjunction with proper door alignment, weatherstripping, and, if needed, a reinforcement kit for enhanced protection.
- Do any of these foot bolts require professional installation?
Most can be installed by a handy homeowner, but kits that are highly specific to a brand or door type may benefit from professional installation for optimal alignment and function.
