Laminated panels are heavy, so tall or wide panels often need a third clamp each side; follow your glass supplier's or designer's layout.\u003c\/p\u003e\n\u003ch2\u003eChoosing the right option\u003c\/h2\u003e\n\u003cp\u003eMeasure the actual glass: this clamp suits 12.76mm, 13.52mm and 16.76mm laminated glass and will not grip anything thinner firmly. On round posts, use a clamp with a curved back. If you want the support pin, order the glass with 11mm holes drilled before toughening and laminating, matched to the pin position on the drawing above.\u003c\/p\u003e\n\u003ch2\u003eFitting and care\u003c\/h2\u003e\n\u003cp\u003eMark the clamp heights on every post with a level line. Drill the post and fix the back half through its slotted holes, then fit the rubber pads for your glass. Set the glass on packers, fit the support pin if used, offer up the front half and tighten the two countersunk screws evenly until the glass is gripped firmly, without overtightening. Use laminated safety glass to your designer's specification. Wipe with warm soapy water; on the coast or by a pool, a fresh-water rinse every few weeks keeps the satin finish bright.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eIs the price for one clamp?\u003c\/summary\u003e\u003cp\u003eYes.
