Step-by-Step Installation for Maximum Durability

Proper installation ensures optimal performance. Start by marking screw holes directly over studs or use anchors if studs aren’t present.

After securing, gently tap the screw with a hammer to ensure full anchoring—this enhances resistance to vibration and load stress.
