Mounting Guidance:

Install using four 3/8” stainless steel bolts (not included). Use ¾” or thicker back bracing where possible. For partition walls or exposed installations, T-nuts or equivalent secure anchors are recommended. For optimal strength, units may be through-bolted back-to-back. Proper locking and anchoring are required for warranty eligibility.

Designed to enclose standard outdoor sprinkler timer boxes. Accommodates conduit runs up to 1/2" (0.8" OD) from the rear or bottom for added flexibility.

Warranty:

All 12-gauge models include a 10-Year Vandalism Warranty. If the enclosure is compromised by vandalism and was properly installed and locked, Vandal Stop will repair or replace the unit — a warranty unmatched in the industry.

Competitor Comparison:

Many competing enclosures are made from thin metal or plastic and lack secure locking systems or weather protection. The AA-ST1 provides superior durability with 12-gauge stainless steel, a lock shroud, and flexible mounting options. Competitors like Orbit or Irritrol do not offer comparable protection or warranty coverage.
