This lets you build precise dimensions by combining blocks (e.g. 1.005 + 1.50 + 5.00 + 20.00 = 27.505 mm) without measurable gap error. Treat them gently — nicks, fingerprints and corrosion ruin the wringability.\u003c\/p\u003e","products":[{"product_id":"cast-iron-vee-block-without-clamp","title":"Cast Iron Vee Block Without Clamp","description":"\u003cdiv style=\"max-width:680px;width:100%;padding:12px 0;font-family:Arial,sans-serif;\"\u003e\n\u003cdiv style=\"display:flex;align-items:flex-start;justify-content:space-between;border-top:1px solid #e0e0e0;border-bottom:1px solid #e0e0e0;padding:16px 0;margin-bottom:24px;\"\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e◆\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eMaxigear\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e●\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eTrade workshop pick\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e▲\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eDependable build\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:14px;line-height:1.6;color:#444;margin:0;\"\u003eThe Maxigear Cast Iron Vee Block Without Clamp gives trades and workshops a dependable, fit-for-purpose hand tool.
