Horseshoe plastic packers for levelling and spacing around bolts and fixings. Slide one in around the bolt without removing it, and the frame or panel sits at true height and square before you tighten it off.
Glazing frames, facade panels, cladding, doors: anywhere a fixing needs a shim in seconds.
Horseshoe shape slides in around bolts without removal.
Levels and spaces frames, panels, and cladding fast.
Plastic packers will not rot, rust, or corrode against aluminium.
Slide the packer in at the fixing point, check level and alignment, then tighten the fixing to clamp it. Stack packers for bigger gaps and keep the load spread, not point-loaded on one corner.
Structural shimming has load limits: use the right packer size and quantity for the span, and never rely on a single packer to carry load.
